I am mad at myself and I don't know what to do - Care to help?

I used to have a nice body, but now I'm overweight and I hate the way I look. My clothes don't fit at all and I feel very sad. I'm mad at myself because of the fact that I let myself reach this pathetic level. I don't know what happened, but my life has always been very stressful and I find comfort in food. I am a strong person and I am clever as well. I hate to feel pathetic like that.

I always follow a diet then break it after a week or two. The thing is my clothes don't fit at all and I feel so mad at myself.

How to deal with such a body until I lose weight?

Any help will be deeply appreciated.
