sister had vbloc surgery..now
You know, I was that sister whose insurance would not cover the surgery. While I watched her lose all of the weight, I was a little bit bitter, a little bit angry, and a little bit jealous. I was also annoyed with her a lot for talking about it ALL THE TIME. But in the end, I was still amazed and proud at her success. Never so much as when she showed me a group photo from some meet and greet and I could not pick HER out of the crowd. It's unfortunate that your sister has had a tough time of things. I don't know the first thing about this v-bloc therapy, but perhaps they can adjust it down so that it's not shocking her so badly. Maybe at some point in the future she will have insurance that covers WLS. If it is supposed to happen, it will. I think I'm proof of that. (I eventually had surgery anyhow, though I was self-pay... or I guess in my case, Dad-pay. ) For the time being, all you can do is help and support one another. There is NO WAY you should feel guilty about having something done that she can't do right now. I think that guilt might end up sabotaging YOU in the end, and then no one wins.
Best of luck!
