What do I do

I just want to be a normal teenager, but I have hs , not just hs, I have autism, POTS, anemia and on top of all of that a chronic wound that’s been open for over a year. All of this at 15 years old, I’m not happy anymore, no matter if I’m laughing or happy at one moment just one thought of any of this makes me realize my future isn’t going to be good. Is my life even worth living at this point?
