Hang in there. It's completely normal to feel that way, I think it would be odd not to feel that. The day of my surgery, waiting to go to pre-op, gowned and IV in place and I was questioning if I should be doing this. I think my husband thought I was crazy. If you're like me, who is at least 100 lbs. overweight, I knew I couldn't live that weight forever. Just focus on the future and how much healthier you will be. Take it one day at a time. It will all be worth it.
