BTW being scared of failure is normal. I had told a lot of people I was having the surgery then started to worry about failure and being known as the fat guy who couldn't lose weight even with WLS......
Failure is not an option for me but the thought of it is scary....normal
You'll do fine just remember to follow your Doc and Nutritionist guidelines. It is OK to set high goals for yourself but please, please keep the immediate expectations in check. You are not going to drop a 100lbs a week after surgery. I don't mean to come off as preaching but we see these posts daily about how ppl have surgery and a month or so later they're pissed because they have lost next to nothing for weight. I was one of those people. I was not prepared like I thought I was. I expected weight to fall off quickly the first couple of months then gradually slow down. Well it was the opposite.
Patience was a tough one for me and still at times. Just remember you did not get to this point over night and you will not hit those goals that way either.
Good luck and all the best!!
