How to stop comfort eating?

Ive been comfort eating a lot recently.
I get cravings in my head for snacks (not healthy stuff) and i cant resisit it.
I have to eat a lot to feel full but i ususally feel a bit sick at this point!!
Ive alos noticed ive gained weight recently too and am a bit fatter!!
How can i stop this and also lose the weight and the fat ive gained?
Im being bullied at the moment so i think that may be causing it.
I also feel really guilt and bad after ive comfort eaten because i know its wrong but i cant help it.
Thanks

I guess if you're comfort eating the best way to stop would be to work out why you're needing to comfort yourself and try to prevent that. Are you stressed or anything?
I comfort ate a bit when I was depressed and it stopped when I stopped being depressed.

I guess trying to distract yourself or eat other healthier foods when you have cravings may help too. I used to have little snacks constantly rather than full meals (I couldn't eat a lot in one sitting). I guess doing something like that may mean you can still snack but hopefully not put on as much weight.

I think the only real way to stop it will be to deal with it at the root though. Have you ever looked into CBT? The base concept may help you. I think comfort eating is probably kinda simmilar to things like OCD in cause (an unwanted ritual or comfort which is triggered by stress) is trand CBT helps with that.
