Did you get any reading material and information packets from your surgeon? Start by going through that.
It's quite normal to get cold feet pre op. You'll probably have roller coaster emotions right up to the date.
Here's something I posted elsewhere for someone who was having the same thoughts as you.
As for your risks and what MIGHT happen post op, and whether you feel that surgery and the subsquent weight loss will help improve the quality of your life, and whether you can stict to the ruled you need to post op, for the rest of your life, is your decision and one that only YOU can make.
If you are having doubts, then please go through all the informative posts in this forum, and search other forums as well.
The discussion going on in the following thread might be a good place to start.

Always keep in mind that there are two sides to any and every coin. YOU are the only one who can choose which side of the coin.
Make a list of what your weight prevents you from doing, what risks you have due to your weight.
Make a list of what you are afraid of happening due to surgery.
Make a list of how you hope to improve your life through this surgery.
Compare the lists, and ponder your thoughts.
