Hi! I'm right there with you. I don't have a specific date for my goal, but I miss being in shape, having clothes that fit, being able to keep up with friends...
And, true - you can't "diet" forever, because labeling something a "diet" is pretty much saying something is temporary. It's like they say - it's a total lifestyle change. I lost 75 lbs when I was 23, and kept it off for 5 years, but it's been coming back the last 2, because I didn't maintain my activity level. I'm still eating pretty healthy FOODS, but that's because I made that part of the "lifestyle" change years ago. However, I still have a tendency to fall into the portions-trap, and the sedentary lifestyle trap. So, I have to work at it.
You really do have to take it just one day at a time. Treat food like a necessity, not your reason for living. And treat exercise and activity as something that's fun and allows you to know you're alive, instead of a chore.
