Gained back weight...how can I lose it and feel sexy again?

As you can see, a lot of us are in the same boat as you. The best way to feel good about yourself is to have a plan and work the plan. As soon as you start this journey and follow the steps, you'll begin to feel better -- because your foot is on the path. Of course this journey should include an appropriate calorie/day goal, stepping up your exercise, weighing all your food, and making food choices that are nutritious and satisfying. It takes a few weeks to establish a habit (such as an exercise regimen), but once you make it a priority in your life, it becomes more important and something that you want to do. You know you can do this; you just need to set out on your plan. The MFP community is very motivating and you are smart to look to it for support...
