I think it is very normal. At some point, you have to relinquish control (or lack thereof) and let the Good Lord (Or surgeon, if you will) take the wheel for you. Yeah, it's scary - and there are tons of opinions out there. I was asking lots of questions before I pulled the trigger.
Motivation? Watch "My 600# life". That worked for me.
Can I eat the yummy foods I used to? Maybe. Have I tried? Nope. Why? Well, I won't be the first to say this, but my body literally doesn't crave them (* most of the time). I've lost 100# in 7 months, lost 10 inches off my waist, I can walk up steps to my office, and I can work on my car without feeling like I'm going to have a heart attack. Also, I can fit in amusement park rides now, something I couldn't do before.
