I agree you probably need more professional help. Your profile doesn't say where you live but I know my friend with anorexia has a great counsellor & also goes to a support group too, all through a hospital referral.
Please stay strong hun & take care of yourself.
Maybe try to find some local support yourself through the eating disorder organisations. I found a couple on the internet for you but there's loads more if you google it.

Look after yourself & let us know how you get on.
Loads of love.
