I definitely understand where your coming from, everyone is right. Get started now. My girlfriend who literally was a blessing from god had gastric surgery 3 years ago. When we met I had no idea that she had the surgery and we just clicked. She has been my saving grace because she knows what its like and she has given me advice and has helped me stay motivated. She has gained 40LBs since her Gastric Surgery because of food, soda and wine. So she said my working towards this surgery is giving her motivation to get back on track herself. They are right, this is not a magic pill, you have to put in work and its best to get yourself started now so it wont be such a major shock and you wont fail. I understand being fat sucks, I hate it but I got to get better and its best to show those doctors that your motivated for post surgery.
