Even if you don't enjoy exercising, try something. After finishing, you will undoubtably feel better. And next time, when you are procrastinating about exercising, don't think about the energy it may take to do this activity. Rather, remember how relaxed and calm you feel afterwards. Don't avoid the problem.
Some people avoid how they feel by engaging in various behaviors, such as using drugs or alcohol.
Others avoid what is overwhelming by, for instance, procrastinating about their schoolwork. If this sounds familiar, recognize that the stress of the transition in your life may be fueling these behaviors. Be aware that if you continue avoiding what is troubling you, the situation will worsen. If you don't catch yourself and make some changes, the circumstance might become too hard to repair. Mourning the loss, conceptualizing the future.
