Surgery in 2 days and scared of failure....

So my surgery is in 2 days and the only thing I keep thinking about is if im gonna fail at this or not. I think I just have such high expectations for myself that it's getting in my way. I have so much weight to lose and its overwhelming at times, know what I mean? I want to wear a size 12 but im a size 26 and that's a long way to go. Im excited im making this decision to have WLS but it's a long road ahead. I pray my body goes along with it all and just starts losing but I realize that I have to make the right food choices as well and get off my butt and workout again. Im gonna have to take it one day at a time and set little mini goals for myself. A lot of my friends and family know about this surgery and I feel like I have to prove to them all that it was the right decision and that It does work....a lot of pressure! I got this!
