Nervous. And trying not to back out. . .

I feel nervous. I'm not sure if I want to do this. But.  . . I AM sure I want to do this. Then I think, maybe I should just have the lap band instead of the GB. But, do I really want to do this twice? The numbers(stats)  are better with the GB, but am I ready for this? What about the kids I want to have in the future? What about when I become elderly and need my nutrients?  What will happen?  Not a good day. I need to feel more ready. My date is set in exactly 28 days!!!!
