"...only places its been noticeable has been my neck/collarbone area, face, legs and a bit in the arms."
The 'only places'? You're doing great! Are your jeans just a bit loose? That doesn't always 'show' when you look in the mirror, but you can feel that.
Keep dancing around your dorm room every night. Get an exercise dvd, one that's not too hard, and do it. My daughter, who has struggled with her weight all her life, swears by yoga.
Drink water before you eat. You'll eat less.
Does your dorm have stairs? If so, use them. Excellent for toning the legs, hips and belly - and free. Once or twice a day is fine to start with as stairs can be hard on the knees. Build up the number of 'repetitions' over time.
Eat foods that are 'fiber dense' - carrots, celery, vegetables, lettuce, etc., not 'calorie dense' - chips, desserts, fries, etc. Fiber dense fills you up. Calorie dense fill you out.
Eat fruit. It's better for you than fruit juice. Generally lower calorie and higher fiber density. If the price of fruit scares you, think of how much nutrition you get from a piece of fruit compared to chips and desserts.
Allow yourself a treat at least once a week. Small portions, of course.
Congrats on the 3.1 gpa!
