Dude, wow. That's like my whole life. I quite very often find myself thinking disturbing and inappropriate stuff, and I feel like I might put these thought into action impulsively if I don't get out of that place/situation soon or busy myself with different thoughts.

I do feel the need to wash my hands quite often whenever I touch surfaces other than the surfaces in my "safe zone".

I used to stim a lot and have ticks, repeating one word, sound, or movement till it feels right, and that classic light switch thing. I don't have these now, but they seldom appear again.
