One thing I’ve found is that I have kind of a fear of repetition. Usually this manifests at work if I’m in a job that’s repetitive. I have this kind of out of body experience where it’s almost like I wonder how long I’ve been there and how many times I’ve done the thing.
And in college I always tried to sit in a random seat for lectures. Any time I felt I sat in the same seat more than once I would start to feel anxious.
I’ve somehow been able to cope exercising, not sure how since I take a few laps around my block when it’s still dark out. I think it might be that I set a timer? I’m not sure, but there are times when I get that anxiety when I repetitive exercises.
I’ve been trying to research online for ways of coping, but I’m not finding much. The link I posted seems to be just an article on phobias in general, and “dittophobia” sounds like something someone just made up.
I also sometimes get obsessive thoughts or compulsions, though I fall well below the bar of an OCD diagnosis. OP, this doesn’t sound like an ADHD symptom. But just because you experience OCD symptoms doesn’t mean you have OCD. You can still benefit from coping techniques that people with OCD use to handle their obsessive compulsions.
