considering weight loss surgery

I just got my blood work back from my OB, and I have PCOS and high insulin levels... Meaning I am borderline diabetic. I have been dieting and exercising for Years and years and could never shed a pound. So I'm considering gastric bypass surgery. My family thinks i am wrong for wanting the surgery... My mom said if I loved my daughter I wouldn't do it... But that's the main reason i want to do it. I want to be able to do fun stuff with her and her not be embarrassed about her fat mom or I want to be able to go to the park and play without getting tired. And I want to be skinny and healthy for the first time in my life. This is something I have considered for the longest time, and now my daughter is growing up and something needs to change. Like I said, I could never lose weight. I have a hormone problem that stops me from being able to do so. I just wanted some support or if you have had this surgery, comment. I'm at a low point in my life and everybody hating on my choice to do this for my daughter and myself has really got me down in the dumps.
