You might check out a book called The Body Image Workbook, which I think is by Cash. It's been pretty helpful for me, although there's too much going on in my life right now for me to be able to say it's fixed me...

It's made up of exercises to help you learn to accept your body, and recognize how much of your body image issues are tied up in other things altogether. It is helpful, though, for me.

Another thing to check out is eating disorder groups, like those run by ANAD. They can be very helpful, just to know that other people feel similar things.

And is that a saddlebred?
