I hate my life and my body

I’m in such a bad place right now. Nothing is working. Why is my body working against me??? I’m a college student with zero friends. I’m a junior and have no friends because I can’t socialize, join any clubs, let alone barely walk 3 mins to class without having 30 minute flareup that lands me in bathroom half the class. Today was my first day taking propranolol and it literally didn’t work. It just made me tired. Once it wore off I had a flare up and now we are back to square one. Do I just need to get used to the propranolol?? Or is my body just not responding correctly to it? If this doesn’t get better soon I may have to go to a mental hospital or something. These are supposed to be the best years of my life and I’m miserable. I genuinely don’t see a point in living right now. I’m sorry for being negative but I need someone to relate to rn
