Re: something very strange
You need to be hospitalised.
You've jeopardised your health for the sake of vanity, and now you've increased your risk of endocrine disorders, heart disease, hypotension, osteporosis, to name a few.
You're probably seriously deficient in zinc, potassium etc
Your stomach has dramtically shrunk in size, due to the lack of food it's been receiving...hence why you can't keep anything down...i'm surprised your stomach hasn't tried to eat itself.
Please seek immediate medical help.
