Finding a therapist or counselor would probably help some, especially if you get to be comfortable with them. My ED started as minor too and it wasn't until I tried to stop that I realized I couldn't. I have quit now, but I have to constantly watch myself so that I don't start again. Some people can quit on their own, some can't, that's why I suggest a T. Some things that can help are to eat more frequent smaller meals. Also try your hardest not to throw up, even when you feel like you can't help it. If you stay around people right after eating the chances of you throwing up are way smaller because many, even when they feel like they can't hold it in, can if there only option would be purging publicly.

I hope you find the help you need, and welcome to PC.

Good luck
