>>54066390I have a friend that kinda bested his autistic tendencies by doing push ups whenever he felt the need to arrange shit in weird fashion or start some of his weird washing rituals, he would just drop down and do 10 or 20 until he was so tired he couldn't do the stuff that was bothering him, apparently it took a lot of will to even start doing the push ups sometimes but it got easier the more he did it
He got kinda ripped for a while and eventually became more functional by the time we were in college, dunno if that could work for you but it seemed to work for him
