Eating disorders

I've been anorexic for about two years now. I'm almost 16.. I tried recovering this summer since my ex bf dumped me because of the disorder.. I've tried so hard but I've relapsed back into it and I don't know if I can ever stop. Does anyone have any tips on how to not constantly think about food and calories and weight? I'm 5'1 and 95 pounds. My lowest was 88 and I'm trying to be 80. The highest I've ever been was 106 and that was before the eating disorder.
