It does not make any differences if the change is good, like graduating from college, or bad, like ending a relationship. Sometimes, stress can be very useful because it encourages us to learn new and effective ways of dealing with change. It is important to find healthy ways of coping with stress, because too much stress can be harmful to the body and the mind.
Mental exercise is a very healthy way to cope with stress.
Two common forms of mental exercise include meditative relaxation and guided imagery. To practice meditative relaxation, find a quiet place so that you do not become distracted. Seat yourself comfortably on a floor, cushion, or couch. With your eyes closed, let your muscles relax. Begin to focus on your breathing.
