Written by Brendan Marshall, Registered Psychotherapist (Qualifying). Brendan is a therapist and founder of Brendan Marshall Counselling. He works with men who are having difficulties with the daily impact of Anxiety and/or ADHD.

It’s just past midnight. You’ve been in bed for an hour, you’re absolutely drained and your mind is going over that awkward thing from 2019, your Thursday to-do list and a conversation that hasn’t even happened yet. You reach for your phone to just have a quick check. 20 minutes later you’re still up and you’re annoyed.

If that sounds familiar then you’re probably looking for ADHD and anxiety therapy in Markham or just want someone to explain why your brain will not shut up. This post will explain why it happens, why trying to force it to stop doesn’t work and what actually does work.

Why Your Brain Gets Loudest When Everything Else Gets Quiet

During the day your brain is occupied with meetings, messages, traffic, noise etc. All that activity keeps the worries and the half-thoughts in the background. By night when it’s dark and quiet your brain finally has the space to bring it all out at once.
It’s like a desk drawer you’ve been stuffing full of things all week. At the end of the day it just explodes open. The email you didn’t get round to answering, something your boss said, your money worries, your general sense of being on top of things in life… all of it comes rushing at you at once and none of it is going to go away at midnight.

Your body plays a part in it too. If you’ve been stressed all day you’re still in alert mode when you go to bed. Your heart might be racing, your jaw might be tight. Your brain takes that as a signal that something’s wrong and starts looking for the cause.

How Anxiety and ADHD Each Keep You Up

Anxiety keeps your brain in problem solving mode. It’s going through a thousand ‘what if’ scenarios, it’s rehearsing conversations, it’s trying to fix tomorrow before it’s even happened. The whole thing feels very useful and so it’s very difficult to stop. Rather than just resting you’re working a night shift you never agreed to.

ADHD works in a different way. An ADHD brain needs stimulation and a dark quiet room doesn’t really provide that. Your mind will just start to wander, from a song lyric to a project idea to something you read years ago. A lot of guys with ADHD will tell you that night is the only time when no one’s expecting anything from you. You end up staying up and just scrolling because it finally feels like your own time. That’s not laziness, that’s your brain just trying to get a break.

A lot of guys have both and the two feed off each other. ADHD has you running around all day, anxiety has you going over everything in your head at night and lack of sleep the next day makes it even more difficult to focus. It’s a vicious cycle.

What Actually Helps (and What to Expect)

Let’s start with what doesn’t work: telling yourself to stop thinking. Try not to picture a white bear for the next minute—you’ll probably think of one right away. Fighting your thoughts just gives them more attention, and your brain often does the opposite of what you want.

Here’s what tends to work better.

Try doing a brain dump earlier in the evening. Spend ten minutes with paper instead of your phone and write down every worry, task, and “what if.” Next to each, jot down the next small step or just write “nothing to do tonight.” This shows your brain the list is safe somewhere else, so it can let go for now.

Give your brain something simple to focus on. For people with ADHD, a familiar podcast or audiobook at low volume can provide just enough stimulation to keep your mind from wandering. Set a sleep timer and avoid anything scary or stressful.
Try naming the thought instead of following it. In ACT (Acceptance and Commitment Therapy), you practice noticing a thought and labeling it, like saying, “there’s the ‘what if’ machine again.” This helps you step back and watch the thought instead of arguing with it. You don’t have to win—you just stop getting caught up in it.

If you’re still awake after about 20 minutes, get up. Sit somewhere dim and do something boring, then return to bed when you feel sleepy. Lying there frustrated only teaches your brain that bed is a place for stress.

Don’t expect a single trick to fix everything overnight. Most people start to notice small changes first, like falling asleep a little faster or stopping the spiral earlier in the night. In therapy, we work on figuring out whether anxiety, ADHD, or both are affecting your nights, and build a routine that works for you.

Who Is ADHD and Anxiety Therapy Right For?

This is for you if you’re a guy in your 20s or 30s who feels exhausted all day and wide awake at night. It’s also for you if you’ve tried sleep apps, tea, or “just relax” advice and nothing has worked. Whether you have an ADHD diagnosis or just suspect it, and nights are the hardest part, this can help.

It’s also for you if you’ve tried therapy before and didn’t get anything practical out of it. You don’t need to be in crisis to reach out. Just being tired of lying awake arguing with your own mind is reason enough.

What to Expect at Brendan Marshall Counselling in Markham

I’m Brendan Marshall, a Registered Psychotherapist (Qualifying), and I help young men in Markham who are dealing with ADHD and anxiety. Living with ADHD myself for decades has taught me how to spot the tricks my mind plays. I use those insights in our sessions, along with ACT and practical ADHD strategies.

In our first session, we’ll talk about what your nights are like and what your mind does when the lights go out. Then we’ll build a plan that fits your actual schedule. You’ll leave each session with something specific to try before we meet again.
I check in regularly to make sure you’re getting what you need, and I’ll challenge you if something needs a second look.

Frequently Asked Questions About Racing Thoughts at Night

Why can’t I turn my brain off at night?


At night, your brain finally has quiet time to process everything it put off during the day. If you add anxiety, which keeps looking for problems, or ADHD, which needs stimulation to settle down, your mind fills the silence by itself. This usually means your brain is overloaded, not broken.

Are racing thoughts at night a sign of ADHD or anxiety?

It could be either, or both. Anxiety usually loops on one worry or “what if,” while ADHD jumps between random topics. Many guys have a mix of both. Only a qualified clinician can diagnose, but noticing your own pattern gives you something useful to bring to an assessment.

What helps with racing thoughts at night?

Write everything down earlier in the evening, give your brain something simple to focus on, and name your thoughts instead of arguing with them. If you’re still awake after about 20 minutes, get up and do something boring until you feel sleepy. These strategies work with your brain, not against it.

Can therapy help me sleep better?

Yes, if racing thoughts are keeping you awake. Therapy can help you notice the patterns that show up at night, figure out whether anxiety or ADHD is behind them, and build a routine that works for your brain. You’ll leave each session with something specific to try that night.
Ongoing trouble sleeping is also worth mentioning to your doctor, since sleep problems can have physical causes.

When should I see a doctor instead of waiting it out?

If you’ve had trouble sleeping for weeks, snore loudly, wake up gasping, or feel tired no matter how long you’re in bed, talk to your doctor. Sleep problems can have physical causes that therapy alone can’t fix. If racing thoughts are your main problem, therapy and your doctor can help together.

If the thoughts ever turn dark or hopeless, call or text 988 (Canada’s Suicide Crisis Helpline) or go to your nearest emergency room.

If this sounds like your 2am, you don’t have to keep lying awake arguing with your own mind.

You’re not broken, and you’re not bad at sleeping. Your brain just fills the quiet with everything it’s been holding onto all day, and that’s something you can work on.

You’ve been trying to fix this at midnight, when your brain is least able to help. Taking small steps during the day can change your nights.
