Stress describes how a person reacts to a situation. Stress does not describe a property of a job, a company, a political climate. Some things you can control, some things you can't, you have to adapt and pick your battles. You can choose how you react to other people and the world you live in, but you probably can't change other people or the world. When you come to terms with that, and realize that worrying doesn't accomplish anything, you can perhaps choose to feel less stressed.
