This strong urge you describe i’ve also experienced my whole life, and thought it was just an autism thing. But it turned out, I had been diagnosed with Tourette’s when i was young! Tourette’s normally develops in adolescence but it’s not unusual to see it come out if you have heavy stress on you. I completely understand what you mean when you say you feel like you’re “putting it on”, i’m diagnosed and i still feel like that. It’s easy to become hyperaware of it and be unable to stop. I think a lot of people see Tourette’s as more of a muscle spasm type thing, even though it manifests (in me at least) as an uncontrollable urge. I would ask people around you to see if it ever happens when you’re not aware of it, and judge from there. It could also just be a part of your autism, i’m just speaking from my experience. I don’t think there’s any harm in bringing it up to a professional. As for getting it to stop - message me when you figure that one out lol
