First off, you need to stop letting food control you. It's not easy, but you CAN do it. If you have any "junk" food or unhealthy snacks in your house right now, get rid of them. If you don't have them there, you can't eat them. Stock your fridge and pantry with healthy snacks and foods so that if you feel the need to binge on something, it ends up being an apple or cheerios or something.
And no, it's not easy, not at first. Even later, while it will get easier, it will never be flat out easy to not be an emotional eater. Once you are that way, it's going to be something you have to deal with your whole life. I'm that way too, so I know. Good choices need to be made at the store so that when you wake up in the middle of the night say, that there isn't that rocky road ice cream in the freezer. And, if you need something sweet around, pick up some weight watchers ice cream snacks for example. They have ice cream bars and little ice cream cups that contain less than 200 calories each. This way, you can have a treat when you feel upset and not feel guilty later for it.
Best of luck, and remember, you can do it!
