Sometimes we take on stress that we do not need to take on. It is important to let go of stress about things that we cannot control or that is not our own. Letting go of things that we can't control is usually easier said than done. It will take some focus and work on your part just to identify the things you can't do anything about. Try writing down all the things that stress you out or make you anxious. This will allow you to better survey your issues. While it is important to care about others in your life, taking on other people's stress does not actually help you or the other person.
