I need help

I have had an eating disorder for 4 years now. I started when i was 15. Im a hardcore bulimic who purges sometimes 3 times a day. I cant keep my food down and I am always constantly hungry and feel so depressed. I actually got the nerve to go to the family doctor about a year ago, but all he did was refer me to a pyschologist. That didnt help a bit. I really want to get help for myself but i dont know where to start. im so young in life and i dont want to torture myself anymore. can someone please give me some advice on where to start getting help?
