You got the job because you can do the work. Then there are weeks where you can't string two thoughts together and you're terrified someone will finally notice. That's not imposter syndrome in the usual sense.
You got the job because you genuinely could do the work. When you interviewed, when you were new and running on novelty and interest, you did things that made people take notice. You know you're capable. And then there are weeks where you can't string two thoughts together, you've forgotten something you definitely should know, and you're quietly terrified that this is the version they'll finally see through.
That's not the usual imposter syndrome story. That's something specific to ADHD.
The problem isn't that you can't do the work
You took the role because you genuinely can do it. When everything clicks -- hyperfocus, genuine interest, urgency, novelty -- you can do it at a level that surprises even you. The problem is that you can't manufacture that state on demand. One week you're executing like someone possessed. Three weeks later you're staring at a task you know exactly how to do and still cannot start.
To the outside world, this looks inconsistent. To your ADHD brain, it reads as evidence: "I must have tricked them. The first version was the exception. This is the real me."
That interpretation is wrong. But it feels airtight.
Why meetings make it worse
Meetings become their own kind of dread. You know you've let something slip -- you just can't always tell what. The update you were meant to have across, the name you've now asked about three times, the detail everyone else seems to be holding without effort. So you mask harder to compensate. You overprepare for some things and completely miss others. The exhaustion of managing the gap becomes its own full-time job running underneath the actual job.
And because the memory failures feel random -- some days fine, some days genuinely alarming -- you can never calibrate how much to trust yourself. So you trust yourself less across the board. The imposter feeling isn't coming from nowhere. It's your brain pattern-matching on real inconsistency and drawing the wrong conclusion.
The inconsistency is the condition
This is what imposter syndrome gets backwards for ADHDers: the issue isn't that you weren't actually good at the job. It's that ADHD performance is fundamentally state-dependent. Your output on a given day isn't a measure of your capacity -- it's a measure of how well the conditions matched what your brain needed at that moment.
The colleague who works steadily and predictably doesn't have more skill. They have more consistent access to theirs. That's a regulation difference, not a capability difference. Not the same thing.
What actually helps
Recognising the mechanism doesn't make the fear go away. But it does change what the evidence means. When the spiral starts -- "I can't believe I couldn't do that simple thing today" -- the useful question isn't "am I actually capable?" It's "what state was my brain in when that happened?"
Tracking your energy and focus patterns over time turns this from a vague reassurance into something concrete. You start to see that the bad days cluster around specific conditions: poor sleep, too many back-to-back meetings, prolonged masking, weeks where the interesting work dried up. And the good days have their own patterns too. Once you can see the pattern, a bad day stops being proof of fraud and starts being data.
The Easy Mode ADHD Toolkit includes a daily tracker built exactly for this -- simple enough to actually maintain, and useful enough to show you your own patterns over time. Eighteen pages, instant download.
If you're in an imposter spiral right now: you're not a fraud. You're a capable person whose brain is in a state that isn't supporting your best work. Those are two different problems. The second one has solutions.
