One of the best ways to deal with stress is to prevent it. For a student, that might mean studying at a regular, steady rate, rather than trying cram just before an exam, or starting a term paper early in the term rather than waiting to the last minute. I'm not saying you are procrastinating, just giving a few examples of things that cause stress in students' lives. Take a look at your habits and see if there isn't a way you can reduce the stress in your life.

You also need to train yourself to recognize that food is not comfort because it makes you feel as though you have no control. Easy to say, harder to do.

Best of luck.
