First of all, Good for you that you are on your way to better health. NO need to be ashamed. I think all of us can name at least 1 thing in our life that we can feel shame over. So YOU are NOT alone. Its ok to feel that emotion, but don't get stuck there. Try your best to focus on better health and feeling great. Being scared is very normal. If you want I will pray for you . I will pray for peace of mind, comfort, a successful surgery and a lifetime of improved health. Remember YOU are NOT alone is this
