Don't keep your feelings bottled up inside. You need to let out your thoughts and emotions, or the stress of holding them in can increase your blood pressure and raise the possibility of other health problems. If you don't have a confidant or friend you can speak to, consider the services of a professional counselor. In every person's life, there needs to be some kind of balance. Living a balanced life is important for stress reduction. Doing too much of one thing, such as work is an easy way to become stressed. Instead of focusing on only one thing, allocate your time and energy to multiple areas.
Try giving whatever is bothering you a number on a scale from one to ten, where one is a minor bump and ten is the end of the world. You'll probably find that most of your daily problems are no more than a five. In other words, they're not worth getting upset about.
