Stress is actually a pretty normal part of college and adult life. Stress tends to result from balancing different aspects of our lives. Schoolwork has to be done, there are financial worries, extracurricular activities that can add pressure, as well as family issues back home, relationships, friends, work, health, and worrying about getting a job or into graduate school after college. Stress is not always a bad thing - for many of us, it keeps us focused and productive.
Stress can be a problem if you find you cannot sleep, or wake up after a few hours of sleep, do not feel like eating, are feeling too tired to do things you usually enjoy, find yourself pulling away from social activities or friends, or get agitated more easily than usual. If you are experiencing any of those symptoms for more than a few days, it is a good idea to call your college health center and ask about resources for stress.
Most adults develop strategies for coping with stress that include exercise, meditation, or regular activities with friends, which are healthy ways to cope with stress. If you find yourself using drugs, alcohol, or risky sex to manage stress, those behaviors suggest some counseling is in order.
