Why Do I Always Stress Out?

To me stress comes from lack of control. When we don't have control we tend to become stressed and when we are finally able to regain that control we tend to become less stressed. This answer isn't proven, its just how i tend to look at life. Hope it helps

The main reason why people stress out is because you have little to no acceptance in your world. Not accepting the fact that you can not control anybody but your self; your thoughts, actions, moods, and behaviors. You can not change people to who, what, when , where, and how you want them to be.
Reciting the sincerity pray often helps relieve stress and helps remind your self that you can only do what is in your power to do. And it goes like this,  "God grant me the sincerity to accept the things that I can not change, the courage to change the things that I can, and the wise to know the difference."
