I start things like a house on fire. Something new grabs me and I'm gone. Days of it. I forget to eat, I'm still at the screen long after everyone else is asleep, and I feel better than I have in months. Then it ends, or it stalls, and I go through the floor.
Fifty years of that before anybody said the word autism to me.
So why do you crash after hyperfocus? Because hyperfocus runs on borrowed energy. While you're locked in, your brain stops registering hunger, tiredness, the dishes, the people you live with. When the focus lets go, all of it lands at the same time. You're drained, the life you ignored is a mess, and the thing that made you feel alive is suddenly gone. The crash is that gap.
What hyperfocus actually is
Hyperfocus is the word people use for that locked-in state where one thing fills the whole screen and the rest of the world goes quiet. It gets talked about mostly with ADHD. Plenty of autistic people know it from the inside too, usually around a special interest. The two conditions overlap a lot, and Autistica's page on ADHD and autism is a decent place to start if you're wondering about both.
I'll be straight about my own labels. I have ADHD, and at 50 I was also diagnosed with Autism Spectrum Disorder (ASD) (plus BPD, which is another story). So when I read about hyperfocus I see myself in almost every line, and I'd bet a lot of late-diagnosed people do. If the ADHD question is rattling around your head, I wrote about AuDHD and the signs of adult ADHD separately.
Why the crash hits so hard
Douglas Cootey, writing in ADDitude, describes the crash as the clarity going and the chaos coming back. That's exactly it for me. While I'm in it, life is simple. One thing matters. When it's over I'm back in the noise, and I'm tired in a way a night's sleep doesn't touch.
Part of it is the body. You skipped meals, skipped sleep, sat in one position for hours, and ran on interest and adrenaline. When those switch off, the body sends the invoice. Part of it is the contrast. Hyperfocus feels good, really good, so an ordinary Tuesday afterwards looks grey. Cootey points out that for people who also deal with depression the dip can turn into something heavier. I've lived that one.
Then there's the mess. Emails. Bills. Whatever I promised people and forgot. Sandra, my partner, who has been living next to a ghost for a week. Walking back into that is its own kind of hard, and the shame shows up right on schedule.
The boom and bust I didn't have a name for
For most of my life this looked like a character flaw. Huge energy at the start, then nothing. Projects dropped halfway. People I'd pulled in with my enthusiasm left wondering what happened to me. The boom-then-crash cycle is bigger than hyperfocus alone, and I wrote about it on its own.
The diagnosis didn't fix any of it. What it changed was the story. I stopped telling myself I was lazy, or a fraud who could only keep it up for a week. My brain runs hot on one thing and cold on everything else. That's the wiring. It still needs managing, and some weeks I manage it badly.
What helps me land
None of this is medical advice. It's what I've tried, and some of it works some of the time.
- Plan the landing before takeoff. Cootey's main point is to expect the crash so it doesn't ambush you. I know now that a big project ends in a dip, so I try not to book anything important for the days right after. Sounds obvious written down. Took me decades.
- Make time visible. My problem isn't focusing. It's that I can't feel time passing once I do. A timer I can see from across the room breaks the spell better than a phone alarm I swipe away without looking.
- Eat on a clock, not on hunger. Hunger doesn't get through when I'm locked in. So food goes on an alarm, like a pill.
- Keep the next thing small. Cootey suggests lining up the next project so you don't spiral. Careful with that one. For me the next project can easily become the next binge. So the next thing is small and has an end. A walk by the lake. Fixing a hinge.
- Warn people. "I'm going under for a few days" is a much better message than just vanishing on the people who live with you.
This is the timer I mean. Silent, because ticking would drive me up the wall.
Time Timer (silent)
Time Timer
My take. Time you can see. A red disc that shrinks. Sounds dumb, works on a brain that loses three hours to one email.
Good to know. Get the silent model. The ticking drives some of us up the wall.
When the crash is more than a crash
If the low after a project doesn't lift after a few days, or it slides into weeks of not caring about anything, take that to a doctor or a psychologist. Crashes stacked on crashes can turn into burnout, and burnout and depression can look a lot alike from the inside. I wrote about what autistic burnout is if that rings a bell. For adult ADHD in Canada, CADDAC's page for adults 25 and up is solid. In Québec, if you don't know where to start, call 811 and choose option 2 (Info-Social).
