I agree with Hamster very much.

Yoga can be an amazing tool, a body mind connection, to build self esteem and confidence in yourself, acceptance of ones strength and weaknesses, and appreciation of the body you have. Not changing the body, but changing the mind. Changes to the body might happen, but that is an after effect and should not be the sole goal. Yoga has given me so much, I think you are worth taking that shot too. And maybe then you will find yourself of sounder mind to make healthy choices in your life and relationships.

It has really helped me deal with eating disorders, bipolar, and all that has already been mentioned. Plus numerous health benefits. It just might help you find you again. I can't really put into words how much it has helped changed my life except to say unrecognizable to the path I was headed down .
