I don't know what to do

so for the past couple of years I've been struggling with eating disorders like anorexia and bulimia but I've always just copped with it and slowly gotten over it, but this time I am really struggling with bulimia. I just can't shake it, whenever I eat something I feel disgusted in myself and throw up then exercise for a couple of hours. I really don't know what to do I just am hating myself 24/7. I have never self harmed until last night when in a burst of self hatred I carved "don't eat" into my thigh. I'm really just losing control. help
