I'm still trying to figure out this site, and really don't know where to start so here goes: I'm 5' 2 1/2", I weigh 310, and I am disabled with multiple ruptured and bulging discs in my back, as well as deal with extreme depression, and anxiety. My back pain has gotten worse than ever with the new onset of numbness in the legs. My dr says we can't wait any longer for me to try to lose weight on my own so that I can have back surgery. He's ordering lap band to be later followed by neuro surgery on my back. I'm overwhelmed and don't even know where to begin. I barely know only one person that has had lap band and I understand that she is now back to her original weight before surgery. I didn't know that could happen. Now I'm even more scared than ever. I do tend to overeat, so if I go thru with this and it fails, I don't know how I would deal with that? I'd like any feedback I can get. I've got to start somewhere.
