I do this as well, if I get a bit of loose skin around my finger nails I constantly pick at it until it goes raw. I wish I could stop myself doing it.
I also have issues with spotlights and car headlights where I seem hypersensitive to them. Regards noise, the noise of people typing loudly really grates on me, as well as the noise of people eating (I literally have to leave the room). But the one noise that I can’t stand is a hand dryer. If I hear it outside the work toilets before I enter, I literally walk to another floor to avoid it, and if I’m in a cubicle and someone turns on a hand dryer I often have to cover my ears.
Another thing that annoys me about myself, so having the need to double check everything, multiple times. I’m a keyholder at work, and one night a week have to lock up the office. The amount of times I go back to double check I closed windows is ridiculous and annoying, but I have to do it.
My eldest nephew has been diagnosed with dyspraxia, and is very clever, but has issues with coordination, and he has issues socialising too. My mum thinks I have something similar, which wasn’t a known thing when I was a kid.
I’d love to go to a DiS meet one day, but again I’m socially awkward about doing that.
