<human>: Can you condense the text into a few key points?

So over the end of high school and then summer, I lost about fifty pounds. It was a huge accomplishment and its one of my proudest moments. But now that I'm in college, it's not the same. I've been here for about 3 months and I've put back on about 15-20 pounds. I'm not exactly sure, cuz I'm nervous to use the scale again. I have a lot more free time now, and I think that's a big issue. Before, I was always either at school or work, and now I only have class a couple hours a day, and I don't have a job. Another big issue is the dorm food. Basically every meal is a buffet, making it hard to reduce the amount of food that I eat. I work out sometime, but I don't have anywhere near the motivation that I did before. Another issue is that for some reason, I always like to be full again like before I lost the fifty pounds. When I was losing weight, I was content if my stomach wasn't full to the max. I know a lot of people gain the "freshman 15" but I think my car is different considering I had just lost fifty pounds.
<bot>: In college after losing 50 lbs, less motivation to exercise, more need to be full, more food readily available, more free time. Need advice.
