Smem826,
I had to understand that it wasn't the diets that failed it was me, my decision. However, the many diets shows your determination to want to change, but that's not enough. Your mind has to be ready. Because this surgery can be added to your list has another failed attempt to another solution to weight loss. It's like going cold turkey. You have to give up something you love, make you feel good, comfort you etc. I believe you can do it, but make sure your mind is ready and stay connected.
