College student trying to get rid of college weight gain!

Hello! I'm a 21-year-old woman from North Carolina, and I'm finishing up my last semester of college. I kept my weight gain from starting college to a minimum, but for some unknown reason, I gained twenty pounds in the past year. I'm now 5'6" and 165 pounds. I entered college at 140, spent most of it at 145, and I should ideally be around 130 (I have a small frame). I've been trying to eat better, but a low budget, busy lifestyle, and the eating habits of my friends are all making it more challenging than it was in high school. I've been trying to go to the gym in the mornings before classes, but I could use some more discipline with that too. I love weight lifting and hate cardio, but I know it's a necessary evil. I've been weight lifting every other day and jogging every other day (when I'm actually going as often as I should.) I'm thinking about trying sprinting instead of jogging because I'm naturally better at it than jogging, and it burns more calories. Unfortunately, the scale has been going up. I know that's probably due to muscle gain, but I'd like to see some more fat loss as well. Hopefully I'll be able to at least get back down to 145 so my clothes will fit. I'm looking forward to talking to everyone on here!
