Not diagnosed, but:

I sometimes have trouble focusing because I’m focusing on my thoughts instead. Most of the time, it’s not noticeable; I try to make it as subtle as possible if I’m with someone and worry about it later, but my mind when I get these thoughts is drained. More noticeable is the insomnia it produces because I summarize and “clean up” my thoughts at the end of the day if I don’t manage to do so during the day. These are the worst days. The best ones are when I can get through them during the day. Does it count as intervening with my “normal day” (note that these are all normal days) if the only person it effects is me? I don’t know but I definitely wish I could have that time to sleep or, you know, be productive or relax in any way.
