First of all word on everything Cassie up there said!
I have battled health issues as well and totally used food to soothe myself during health crises. It was a never ending cycle that made me feel worse and worse. I'm sorry you are having such a tough time. One thing that might help is to know that you won't always feel this way and that you have made a positive step by reaching out for support. That is awesome and something not everyone has the ability to do.
Baby steps are the way to go (even though I know this I get so antsy with the baby step process.) In time I hope you can learn to love yourself.
