A small while ago I thought I had Tourette's syndrome because I have some tics/ticks. I was confused, because I typically only have them when I'm  overwhelmed. When I get irritated my hand shakes or my head will twitch to the side or my arms have almost a muscle spasm and i clap. There's a clash of a lot of things that happen when I'm overwhelmed. But I read someone that BPD can also cause stress related ticks? Anyone else also have little obsessions with certain body movements, like nose twitching, eye rolling (maybe to the point of them hurting), or grunting? I'm very confused about these kinds of things.
