no time for fitness..

I have heard of the freshman 15. They say that most freshman gain weight their first year of college. This is my second year at Triton college and I also have gained some weight. Before starting Triton I always had a gym class in school. I took that for granted. I used to believe that it should be up to the student if they want to take gym class or not. Now my opinion has completely changed. I miss having gym. I was always fit and didn't think I need to exercise. I didn't put on that much weight maybe 10 lb but it still makes a difference. My body doesn't look the same as it used to. I tried going to the gym everyday. I worked part time which made it easier for me to maintain work, school, and going to the gym. Now that I work full time and I'm a full time student I haven't stepped into the gym in 2 months. There is just not enough time in the day. Also my eating habits switched from eating healthy small portions every 3 to 4 hours to eating fast food twice a day and unhealthy snacks at home. I really need to figure out how to balance everything out. I have my school and work pretty much worked out but I am still struggling with putting my health into the equation. I was wondering if anyone has the same problem and some good ideas that can help me out.
