I cant stop over-eating and I'm gaining rapidly. Halp?

I would also think about cleaning out the cupboards, pre-weigh and pack meals for the next couple days and prelog everything a few days in advance so you have a plan in place to follow. You're at an advantage because you've done this before. You know the healthy snacks that worked for you, and you're already active. You've got this...you just have to start

Trying to find other ways of coping with the stress like exercise, talking to a Friend/therapist or even just getting outside for a bit of fresh air might help you cope with the urge to comfort eat, i would definitely talk to someone about the way you're feeling it will probably make you feel better and ready to solve the problem before it gets out of control - good luck
