As a licensed Counselor for years, I can tell you that most stress is self induced, and dangerous. It affects your health, your quality of life, and your outlook. Stress is usually caused by two categories, Things you can't do anything about or control, and those that you can control and do something about. Dismiss the first. Recognize the fact it is out of your control and move on. The second, too involved to deal with here, but if you recognize the problem go about fixing it, make a plan, and work toward a conclusion. If anger is at the root of your stress, now that's the tough one. You have to work on forgiveness. If you stop and think about it, anger is self-defeating. It hurts only you and your health. Think about forgiveness, making amends, or just moving on. Remember, YOU are your own worst enemy. Nobody else can come close. Hope this helps. Have peace and enjoy life.
