eating disorder

i am 19 years old and i have been struggling with anorexia, bulima, and depression since i was 15 years old. I know that its such a burden on my mental health to always be thinking of what i eat and when i do eat feeling guilty and getting depressed about it, even if i do spew up. The most satisfying thing i get out of in life is being on the scales and weighing less and less everytime. I honestly dont think theres any major cure for it, because even if you do put on weight and dont think about it as much, it will still be there and you will never really be happy with your body. I have had 2 friends that have been to hospital because they suffered from anorexia and even though they have put on weight and are still under normal weight and look skinny, they still think about there weight all the time. However i am really worried about my depression, because if i eat i get really depressed and self harm myself, like in the past week i have slit my wrist, cut my knees and burnt my self all over my arms with cigarettes. Its just really fucked up.
