I felt this exact same way before my surgery . I would think of the worst things and even reconsider if i should go through with it or not. Im now 12 days post op and I'm so glad I went through with it. I worked myself up about it so much and honestly it wasnt as bad as I thought it was going to be at all. Its definitely not easy and has its challenges of course but just know that you are going to be fine. You can do this and once you do you will be so glad you made this decision . so hang in there !
