Kelly, I gained about 25 pounds in college (freshman 15 yea right!). I tried to keep in mind that I grew up on a dairy farm and was very busy with work my whole life, then got to college and slept 12 hours a day. Regardless, I lost the freshman weight, then started gaining it back my last year. The summer after I graduated I finally took an oath to get healthy and it's been working in my favor ever since. Congrats on tackling your health along with college, I personally always took 12-18 credits, worked at least one if not two part-time jobs, and still tried to have a boyfriend or see friends, it was hectic.
We're all here to support you and help you reach your goals. I'm typically pretty disciplined but the days when I'm really down in the dumps and I want something unhealthy to eat and feel like skipping workouts that I log on here. Even if I don't jump on the forums, I love the journal feature of the fitday account. It let's me pour my heart out, then I get up and go for a walk at the very least so I don't fall off the wagon. It's not easy, but if you really want it, success will come your way. Best of luck!
