How did you get help from medical professionals and get taken seriously

TW: I’m at the point where I’m incredibly underweight, my hairs falling out, my pain is after and I can’t keep anything (solids or liquids down) I have a letter from my GP and mental health professional saying that “I’ve reached the ceiling in terms of community care”. I’m scared the hospital will just send me home again. Is there anything that has helped you get the results and help you deserve?

Thanks so much
