Well I kinda understand now why P ate all her pain and became obese. You get knocked up by a guy when you're young, the guy marries you only because there's a child, he's not home most of the time because of work, he then goes and cheats on you, you have another child with him and discover she has autism, you then discover your husband's affair produced a child and the mom wanted child support when you two can barely support your own family. It's a tough life and food seems to have been her escape. Surgery won't change anything if she doesn't fix the reasons that made her eat in the first place, which requires therapy. Now I don't know if she ever got help, but she needs some if she didn't.
