College/Work Stress, finding time/motivation for health and fitness

Hello, my name is Jessica and I'm a junior in college with two jobs. I am off and on with working out and eating right, but this last semester I really did not eat well enough or work out enough (especially for the food I was eating). I already wanted to lose only a few pounds, but I gained almost 15, so now I have more to do! I am very motivated in school and in my jobs, but I really lack motivation when it comes to health and fitness. It'll be nice to meet someone new, someone in the same situation, or anyone who is willing to be helpful or offer some sort of positive feedback!
