So proud of you! That's awesome that you've found a healthy outlet to express those feelings. Exercise definitely helps with the really strong emotions, I've found. Running until you can't breath anymore, and you feel exhausted and dog tired....is surprisingly comforting. Personally I think it's because I finally feel the same physically as I do emotionally. And it's a good, healthy, outlet and coping skill.
I understand the almost bullimic thing too. I'm in kind of the same boat. Working through it. And it's so hard when you just feel so so guilty for eating. But one thing a nutritionist once told me is that I kept thinking of food as a poison and I needed to start thinking of it as an antidote instead. It actually helped a lot.
good luck with everything, friend!
