Your anxiety is TOTALLY normal! I'm a mom, I get it. I was pretty terrified too. But I am now 10 months post op and have NO REGRETS! You will get through this!
I want to piggy back on the person who said there is no safer place than an OR table. I agree. If your surgeon thought there was a reason why you might not make it, and that the risk was greater than having a successful outcome, they wouldn't let you have surgery.
I know you are scared...but do it anyway. Conquer the fear! You're going to learn so much about yourself and your capabilities after this surgery. It's as much a self love adventure as it is a weight loss one!
