I'm sorry to hear that you are going through this. I'm probably NOT the best person to answer this but I'll give my 2 cents. Maybe you can distract yourself so when you feel the urge to eat, you can do something else. Also, you should try to identify what is "triggering" you to eat. If you aren't able to identify it yet then you can still try to distract yourself. Some examples would be you feel the extreme and uncontrollable urge to eat so you do the following:

1- go for a 20 minute walk. If you still want to eat after then eat.
2- watch an episode of a tv show. If you still want to eat after then eat.
3- do 25 crunches/10 push ups. If you still want to eat after then eat.
4- read 1 chapter in a book, call a friend and talk for 15 minutes, check your emails, take a shower, shave your legs, do your nails, get in a car and drive somewhere, do multiplication tables, blow dry your hair, do dishes, do laundry, iron your clothes, rearrange your closet, etc.

Just do something that distracts you from eating and see if you can last at least 20 minutes. If after you do something to distract yourself you still feel the extreme urge to eat then eat. But keep in mind you are practicing self control by distracting yourself.
