Surgery date

Well, I went to the cardiologist for my angiogram, and he found that my heart was not as bad as he had thought or as the echo's had shown, and he cleared me for surgery. I now have a tentative date of Jan 26 (less than 2 weeks).  I am starting all over with the nervous feelings and starting to second guess the decision to have it done. I have thought it out and I'm sure it is the right decision. If I don't do it, I may never know what it's like to be at a normal weight. I still may not make it to a normal weight, but I believe I will at least get close and will be healthier and more active. I also think it will help me avoid diabetes since my mom and bro both have it. I am really needle shy, so I just cannot get diabetes. I can take getting needles at the hospital and stuff, but I would never be able to give myself or anyone else a shot.Everyone please pray, and help me through this nervousness.
