When I discovered I was ADHD at age 40, I was shocked. I'd started to suspect it myself, but it wasn't until a colleague confronted me about my ongoing struggles with paperwork that things really started clicking.
He said, “You do realize you're ADHD, right?”
I remember thinking, Wait, what? My husband and both my kids are ADHD. I know ADHD. How could that even make sense?
When I started asking friends and colleagues if they thought I was ADHD, one person responded, “Oh, I thought you knew!” I thought I was pretty self-aware. After all, I was a psychologist who had been through therapy myself. How had nobody brought this up before? How had I missed it? I went through a bit of an existential crisis. Suddenly, I was looking back at my life differently, and there was so much to learn about ADHD that I didn't know where to start. If you've recently discovered you're ADHD or are wondering if you might be, I know how overwhelming all the information can feel. I've put together some of what I've learned personally and professionally, along with a few resources to help you make sense of it all.
For those who enjoy going down huge information rabbit holes, I also have a more extensive Adult ADHD Resource Library.
Processing Your ADHD Discovery
Learning that you're ADHD later in life can be a lot to process. You might feel relief, grief, anger, excitement, or some combination of emotions. It can answer questions you've had for years while bringing up a whole bunch of new ones.
For me, this discovery completely changed how I viewed my past. It reminded me of watching The Sixth Sense. Once you know the twist ending, you want to go back and rewatch the whole movie because suddenly you see things you missed the first time.
Helpful resources for processing your ADHD discovery:

Okay, I'm ADHD. Now What Do I Actually Do?
You don't have to figure everything out or make a bunch of changes right away. I'd start by noticing where ADHD is making life harder than it needs to be. Maybe it's getting started on tasks, keeping up with household responsibilities, managing your time, or getting overwhelmed by things other people don't seem to notice.
Consider experimenting with accommodations instead of continuing to force yourself to use strategies that have never worked for you. You might also want to explore medication with a qualified prescriber, ADHD-informed therapy, or coaching, depending on what you're struggling with.
And you don't have to tell everyone about your ADHD right away. Take some time to decide who you want to share this information with and whether doing so would actually be helpful for you. Connecting with other ADHDers, whether through online communities, support groups, or friendships, can also help you feel less alone and learn from people who share similar experiences.
How Was My ADHD Missed?
Once I started learning about ADHD, I began looking back at my life and realizing the signs had been there all along. My report cards were full of comments about talking too much and not staying in my seat. I was always losing things, putting projects off until the last minute, and staying up late to finish work I'd had weeks to complete. Looking back, it seems pretty obvious. So how did everyone miss it, including me?
For a long time, ADHD was primarily associated with hyperactive little boys. Girls who did well academically or learned to compensate for their struggles were often overlooked. Apparently, getting good grades was enough to keep people from asking too many questions about how I was managing to get them.
I even had a fellow psychologist tell me, “You have a PhD. You couldn't have completed college successfully if you were ADHD.” At the time, I thought, Well, that makes sense. How could I have done so well in graduate school if I was ADHD? Turns out, they were wrong!
Like many women whose ADHD went unrecognized, I was told I was “just” anxious or depressed. ADHD in women is often overlooked because our struggles get attributed to anxiety, depression, or other mental health concerns. And while those conditions can certainly coexist with ADHD, sometimes ADHD is the missing piece that nobody thought to look for.

What About Trauma? Doesn't That Explain Things Better Than ADHD?
I've worked with clients who've spent years in therapy understanding their difficulties with attention, distractibility, or sitting still through the lens of childhood or complex trauma. And while trauma may absolutely be part of their story, sometimes ADHD hasn't even been considered.
ADHD and trauma can overlap in how they show up, and they can also coexist. Recognizing ADHD doesn't mean the trauma wasn't real or important. It may simply provide another piece of the puzzle.
For more on this, read my article Maybe It's Not Just Trauma.
The Shame of Growing Up With Unrecognized ADHD
When you spend years being told you're lazy, careless, too sensitive, or just need to try harder, it's easy to start believing those things about yourself. I remember getting so frustrated with myself when I'd forget to move the laundry into the dryer and have to wash it all over again because it smelled. When my mom visited, she'd tell me, “The trick is to fold the clothes right after they come out of the dryer.” Meanwhile, I was thinking, I can't even remember to get them INTO the dryer, let alone fold them!
Even after discovering you're ADHD, those old beliefs don't necessarily disappear. One thing I've noticed in my work with late-identified ADHD adults is how much shame people can carry about things they've struggled with their entire lives. Understanding why something is difficult doesn't automatically undo years of feeling bad about yourself.
Helpful resources on ADHD and shame:
ADHD, Motivation, and Procrastination
When I was working on my dissertation, I was completely overwhelmed. The whole project felt enormous, I was bored with it, and I was so sick of doing revision after revision that I could barely motivate myself to work on it. My husband once came home and found me scrubbing the trim around the house instead. His response? “Ah, I see you're procrasti-cleaning again.”
I knew I needed to get myself to my office on campus to work, but getting there was half the battle. I thought taking a workout class in the morning might help. Nope, the snooze button won every time. So I eventually enrolled in a 7:30 a.m. tennis class that I would actually get a grade for. If I didn't show up, there was a consequence. Apparently, that was what it took to get me out of bed and onto campus!
That particular strategy worked for me, but it certainly wouldn't work for everyone. A lot of the motivation advice we're given doesn't account for ADHD-related difficulties with getting started, staying engaged, or following through. I hear clients say things like, “I just need more willpower,” or “I need to be more disciplined.” I wish they'd stop being so hard on themselves. They've often spent years trying to force themselves to do things in ways that just aren't working.

How ADHD Can Affect Relationships
My husband sometimes gets frustrated because I'll walk away while he's talking to me. In my defense, I'm usually still listening! But I'll suddenly remember something I need from another room and go get it before I forget what it was.
My husband is also neurodivergent and struggles with rejection sensitivity. When I walk away, it can really hurt him. He experiences it as me dismissing him or not caring about what he has to say, even though that's not what's happening on my end.
We also have different sensory needs. He loves having background noise on, while I can get overwhelmed by it. And then there's the mental load of remembering things, like having to remind him to make appointments for himself. Even when we understand why these things happen, they can still create frustration.
Understanding how our different neurodivergent traits interact has helped us recognize what's happening and talk about it. It doesn't mean the hurt feelings or frustration magically disappear, but we're better able to understand where each other is coming from.

Learning to Work With My ADHD
When I was struggling with paperwork at my previous job, my employer suggested I use a checklist and go through everything step by step at the end of the day. Sounds reasonable, right? Except I knew myself well enough to know I'd probably never look at it.
When I tried forcing myself to use one, I was still missing things. I remember my heart racing as I went through that checklist, terrified I'd overlook something again. How could I keep making these supposedly “careless mistakes” even when I was trying so hard to get everything right?
I've gotten similar advice throughout my life. Just put your keys in the same place every time you get home! Great idea, except somehow mine would end up in the refrigerator because I got distracted along the way.
One of the biggest changes I've made is working for myself. Having my own therapy practice gives me more control over how I work and what accommodations I use. For example, I've never liked making phone calls, so I handle scheduling through email or text instead. I also use technology to help with writing and paperwork, rather than continuing to struggle with those tasks the same way I used to.
I'm still figuring things out, and what works for me doesn't always work for another ADHDer. But these days, I have a much better sense of what I need and the flexibility to do things differently.

Late Diagnosed ADHD in Adults: Frequently Asked Questions
-
You don't have to figure everything out at once. Start by learning about ADHD and noticing how it shows up in your own life. You may find yourself looking back at past experiences, questioning old assumptions, or recognizing needs you hadn't considered before. Give yourself some room to explore without feeling like you need to change everything immediately.
-
Yes. Many people are both ADHD and autistic, which is often called AuDHD. This can feel confusing because ADHD and autism can sometimes pull you in different directions. Your ADHD side may crave novelty, stimulation, and flexibility, while your autistic side may need predictability, routine, and recovery time. Understanding both can help you stop blaming yourself and start building support that actually fits your brain.
-
Yes. Many people notice that ADHD challenges feel harder to manage during perimenopause or menopause. Changes in estrogen can affect attention, mood, sleep, motivation, brain fog, and emotional regulation. This can be especially confusing if you were recently diagnosed with ADHD because you may be asking, “Was it always this hard, or did something change?” Sometimes the answer is both. ADHD may have been there all along, and hormonal changes may make the coping strategies that used to work feel less reliable.
-
Yes. Therapy can help you process the diagnosis, untangle shame, understand executive functioning, work with motivation instead of against it, navigate relationships, and build systems that fit your actual brain. ADHD therapy should not be about forcing you into a neurotypical mold. It should help you create a life that works better for you.
-
No. I believe self-identification is valid, and you don't need a formal diagnosis to explore your ADHD or find support. However, ADHD overlaps with other conditions, so working with a neurodivergent-affirming therapist can help you sort things out. Formal testing may also be useful for medication or certain accommodations.
