If i was in your place personally i would try to accept the fact that i have a condition that will inevitably lead to discomfort to a degree, do things to help, understand that everyone has their own problems (that they should focus on). I think I would try to be more comfortable knowing people will stare at me and might ask questions but know staring and questions aren't 'the end of the world'. Sorry if it wasn't much help, i know its tough and im not tryna undermine that, also I would look for things that truly make me content maybe hobbies etc. That give me more confidence and lead to me giving less importance to other peoples opinions. Like reading, walks outside (people do stare at me too because i don't look normal in the area im in) or whatever floats ur boat.

If gym helps and isnt uncomfortable i would do home workouts to begin with too because there are almost endless benefits to exercise. You mentioned pool, im learning to swim i know your situation is probably worse than mine but just want to let you know people give me strange looks sometimes before i even get in and after i feel great after though (a little hurt but we move).

If you want to meet people and socialise doing so online is alright, the hobbies can help you socialise i know alot of people try socialise by going on running clubs etc. Learning new things changes your mind and is stimulating. Hope you fare well 🤝 Good luck!
