Eating disorder

I need help/advise. I thought I had it under control but I’ve slipped. I’m trying so hard but no matter what I do I don’t feel normal. I’ve lost a stone in weight in a healthy manner but the last few weeks I’ve struggled to keep my bulimia at bay and I’m terrified. I want to be healthy and I’ve been so proud of myself so why am I feeling the urge to throw up everything I eat again. I don’t even eat that much.
