It's good you found an online support group, then! I just joined as well. My surgery is on December 28, and my husband, mom, and 2 friends know and are being very supportive, but I'm waiting until after the surgery to decide if I want to tell more people, so I definitely want the online support as well.
My biggest concerns right now are the liquid diet (terrified I'll be hungry the whole time), and that I'm supposed to try and lose 1-2 lbs/week before the liquid diet, which I've been trying to do for over a month with almost no success. I'm great at planning out my food for work all day but then I'm starving when I come home and eat too much. My surgeon says not too worry, the liquid diet will be very effective, but I'm nervous about being able to even DO that diet. Ugh.
