I think nerves are normal, especially with a life changing surgery such as this. I haven't had my VSG surgery yet, but I've been considering it for a year and a half and finally committed to the process. The main thing holding me back? I was TERRIFIED of anesthesia. I would cry, shake uncontrollably and picture myself not making it through the surgery at the thought. In February, I had to have surgery on my foot - there was no choice. I had never been put under anesthesia before and I felt like my worst nightmare was coming true by feeling like I had to do this when I was so scared. I made myself sick with worry for the two weeks prior to surgery. I considered backing out even though I knew this surgery HAD to happen. Once surgery day came, it was like the blink of an eye and it was all over. I woke up in recovery wondering why I was ever afraid in the first place, feeling proud of myself and kind of ridiculous for worrying, too. My FIRST thought was, "oh my gosh, this was so easy...I'm going to have my VSG!!!" and as soon as I recovered, I began the VSG process.
Personally, I feel there is a HUGE difference in being afraid of the actual surgery it's self and not being committed to the process afterwards. If you're doubting your ability to live the lifestyle post-op, I would definitely postpone the surgery until you are absolutely positive this is what you want for your life. If it's just a fear of the unknown, fear of the pain involved, or fear of the anesthesia, please don't worry. I know that it's so much easier said than done, and I understand that fear is a very real thing, but just think of how proud of yourself you'll be when you wake up and are able to start your new life!
