Hi there,
As far as advice.. this is YOUR body and YOUR life. You have to make the decision for what is best for you, not them. When I first told my Mom about wanting WLS, she kindof said "yeah uh huh" and didn't think I was serious about it. She used to tell me all about how she was able to lose 80 pounds without surgery.. blah blah blah. She was 180 pounds at her biggest, and here I was 365 pounds trying to explain it. She never took it serious until I took her to a WLS seminar. She sat there and was supposedly there for moral support, although she wasn't paying attention and was reading a book while the speaker was doing the presentation. Then, when the surgeon got up there, and explained how people with a BMI over 50 were more likely to die very young from being obese, she actually leaned over and asked me what my BMI was. When I told her 61, she looked shocked. From that moment on she paid attention, and realized that this was not only a good decision, but something that would work for me. From then on she took me to every appt I had, (my doctor was 2 hours away) and she even went down to stay with my kids in the hotel while my husband was at the hospital.
Alot of people won't understand, (and frankly they don't have to) and some people will just think you took the "easy" way out. Well, they don't have to live in your shoes, or live with being the size that you are. It's not easy. For me, I had to surround myself with the positive people, and the rest of them could go fly a kite. I still have people in my family who can't believe I had surgery, and they tell me they think I was crazy. I tell them "hmm.. I lost over 150 pounds, and am healthier then I have ever been... so while I respect your opinion, I think it's stupid."
Do this for YOU... and forget everybody else.
