Last Appt then approval process...NERVOUS

Well my last appt is next Wed then on for the approval process. Dr says I have to be on the liquid diet for 4 weeks prior to surgery for the way I carry my weight. I must say I am getting very nervous now. Have read alot of the blogs and how some people are have great success and some are having nothing but problems. I pray that I will be a success story I need this for myself as well as my family, I need to be around for my children so this is a MAJOR step in my life. Have lost 35 lbs so far just by not drinking sodas and no real sugar and eating smaller portions and for that I am proud. But I have over 200lbs to lose and just hope choosing the lapband is the right decison.

Several people I know have had gastric bypass and have dropped all there weight in a years time and others who have had the lapband are still trying to lose all there weight. My Dr has told me if I follow everything in 2 years I will be at my goal and I am excited about that. Just nervous with all the what if''s and the unknown. Its taking years to put this weight on and I know it wont disappear over nite even though we all wished that

Does anyone have any advise on getting over the nervous problems and to be confident this is the right decison for me?

Thanks!
