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.
OCD is a very complex diagnosis, and I’m not even saying OP has it, just that they are displaying symptoms. Obsessive thoughts and compulsions do not always revolve around repetition, that is only one of many possible symptoms. Much like ADHD people experience ADHD differently, people with OCD have different symptoms.
ETA: compulsions involve feeling compelled to do something in order to alleviate feelings of anxiety/doom that something bad is going to happen. They often manifest as repetitive behaviors in most people with OCD, but I’m not here to diagnose OP. I’m just saying they are showing symptoms, and they could benefit from coping techniques that target obsessive thoughts and compulsions.
