Genuinely how am I supposed to cope with being disabled for the next 60+ years

17 years old and was crying from the pain im in today. I tried to play some games with friends online earlier and my shoulder was too sore from just holding my arm out to use a mouse and keyboard. My mam spent hours slow cooking chicken broth for me and i was too sick to eat it. I'm crying just writing this I really cant go on.

I was supposed to have a whole life and now im housebound from going out with friends. I'm supposed to be a teenager. I dont know how I'll get a job or continue school.

I was fine mentally before my health declined so fast a year ago and now I cant go a week without crying from either pain or the idea of having to deal with this pain for the rest of my life
