New me for the new year?

Okay, so I'm looking for a little advice here. Not going to go into a lot of boring details, but I spent 5 years in a mentally/emotionally/physically abusive marriage. Came out of it being basically brain-washed into thinking I was unattractive and disgusting. Spent almost a decade single because I believed that fact. I'm now in a loving relationship, but still have trouble seeing myself as a worthy human being. It makes me less enthusiastic in the bedroom or to even just go out somewhere. I would love to be able to accept my bigger frame and feel at least a little sexy now and then. I can only see that benefiting my current relationship. Any bigger girls out there have pointers on how they accepted themselves, or anyone bounce back after a bad relationship?
