I understand where you're at right now. I'm there right along with you. I had lost 80 pounds about 4 years ago and kept it all off for over 2 years. Then, I started gaining weight, probably due to not controlling portions. After that, I got pregnant and gained 50 pounds during pregnancy! I only lost 20 pounds after the baby was born. The rest will take a lot of work, I know. The best advice I have is just take it one day at a time. Praise yourself for the small milestones, and don't let people like your friend in a size 0 get you down. You are healthier than she is, I guarantee it! Just remember, skinny people who eat crap their whole lives end up having heart attacks and clogged arteries by the time they are in their 40's a lot of times. I'd rather have the metabolism that is slow to warn me when I need to work on my diet/exercise, than to be "skinny-fat" on the inside and be rotting away faster with no weight gain. Hang in there....
