I'm so sorry to hear what you've been through and I think for you to have come out of that so strong indicates that you are a determined person.
My only suggestion for you is...LOVE YOURSELF FIRST.
Please see a professional therapist and finish dealing with your luggage first. Only hen your heart and soul will ACCEPT AND UNDERSTAND someone else's love for you. If you steal doubt yourself or you body pleasing someone, it MIGHT indicate that you're not completely through your depression yet.
I had a situation almost similar to yours. Until recently I didn't even understand why anyone would like me in the first place. It's something I had to deal with through thorough sessions with the therapist and an adequate treatment.
And now what I don't get is why wouldn't someone like me?!?. LOL
Weight loss doesn't solve all of these problems. Curing the heart and soul does at times and is the beginning of success in the rest: LOVE and WEIGHT.
Good luck to you!
