When I try to do something new with my body, like an exercise or dance move I've never tried before, I get so freaked out that I'm doing it wrong that I'll start to feel extreme dread and panic and just need to stop. I usually will become very depressed immediately after and start to cry and just want to curl up into a ball.

I almost never do new things around other people for that reason. I've never broken down and cried in front of someone over it, but I've wanted to. I have to excuse myself, or tell them I'm tired or make up some reason for why I don't want to do the thing, without saying that I feel awkward or I feel like I'm doing it wrong. The feeling is so strong that if I articulated it I would cry, so I just need to act like it's no big deal.

But it seems like it is. Even by myself I can't even work out or do stretches without bringing on a break down. Which of course means, I just sit in a ball on the couch all day.

Is this a thing that other people experience? Any advice?
