trauma survivor need help...

Hello everyone my name is Sabrina and i will have surgery on 10/21/08. I am very scared!!I am a survivor of trauma,and i suffer from PTSD.I have major issues with my body image and i'm trying to get my life back.For so long i did not care about my appearance and really wanted to gain so much that no one would even look at me, disappear into the weight.I really need alot of support so i can start this journey and not allow my attacker to win.I think i'm making a great decision but i am very scared....my daughter has been very helpful , she manage to get me out of the house and attend different events but i am very afraid of going anywhere other than work and home.Food has really been my comforter.Any suggestions on how i can make it through this surgery?any suggestions on coping skills to substitute food?i welcome any advice..
