i just wanted to say that i know how you feel. i binge and purge and even though i know nutrition and was a physical trainer once, it's still something i struggle with. I'll eat healthy during the day and then night comes and all my sugar/junk food cravings comes, and all my good work during the day goes away. then i feel so guilty, i make myself throw up, which i know isn't the answer. i hate looking in the mirror, getting dressed and having to go out and be social. it's an irrational fear but one that is very real.
I don't have the answer, other than sometimes when i have the energy, working out seems to temporarily help.
Just know you're not alone and this is a good place for support. so welcome.
