Struggling with Binge Eating and Anorexia

I’ve always been the restrictive type of anorexic… but today and yesterday I binge ate some high protein cookie dough. I felt so guilty I couldn’t sleep last night and I probably won’t be able to sleep tonight either. I felt so out of control and I’m concerned I’m going to gain weight. I don’t know what to do because I don’t want this to be a pattern. I know that my binges aren’t even bad, maybe an extra 300 calories TOPS, but I work so hard throughout the day to stay under a certain amount and I feel defeated when I go over. I’m so depressed. All I think about is food, it’s all over my social media feeds. My brain is driving me insane.
