Does somebody know how to help me?

I don't know where I should post this but im desperate and need help on something i dont know how to solve.

I'm extremely ill. My intestines are screwed up, I have scoliosis, I'm malnourished, I'm convulsive and god knows what else.

I lost 40kg in less than a year (I weigh 44kg now), my stomach can't keep any food inside it, I'm too weak and tired to even stand up, I faint often and I have fevers every week. Today I had hypothermia. I had a ministroke recently and nearly died. I feel like I'm only alive out of will, I want to be alive. But my family has ways been negligent, and now that I'm 18, I officially can't count on them for anything. I don't have a job and I don't study because my health doesn't allow me to do so. Doctors don't care. They blame me saying a young person can't be sick, "it's impossible", and that there's nothing i can do. "You should just go home" "seek psychiatric help, it must be anxiety" I've been like this for more than a year and it only gets worse.

I need medical help, I feel like I can't even live anymore. I want to find a way to make them take me to a hospital. I can't eat by myself I can't walk by myself. I don't wanna die. How do I cause something that'll make them admit me in a hospital? I don't wanna attempt su1c1de because then I'd be in a psychiatric ward. I've been there and that's not what I need. What can I do? How do I cause a situation in which I can go to a hospital?
