Hi, this may sound silly, and it's possible that I've posted in the wrong area. But I was wondering if anyone, pre- or post surgical has worried, or feared that the surgery wouldn't work for them? My surgery is Aug 25. I've been significantly overweight most of my adult life. I've been successful once at losing weight and keeping it off for years, but then got arthritis in my knee and gained about 50 lbs back. I find myself stressing out about the surgery. What if I've wrecked my metabolism, and I get it done, and follow directions and don't lose any weight. Is this even possible? Maybe it's just irrational fear. Maybe it's my fear of failure. Is this common? Does anyone else ever feel this way? If you've had surgery, what was your outcome? I guess all this feels a little "too good to be true". I've had some success in my pre-surgical dieting, losing 15 lbs since 2/27. Most of which has been since June 9. I'm anxious, I'm excited, I'm a little scared and mostly I'm just ready to get on with my healthier, lighter, happier life.
