4) Spend a lot of time focused on things you can’t control.
Worrying will wear you down under the best of circumstances, but if you really want to ramp your frustration level up to 11, spend your time worrying about things you can’t control. What kind of mood will someone be in tomorrow? What if your child gets sick? What if your boyfriend doesn’t like what you cook him for dinner next week? Getting upset about these sort of issues allows you to combine a sense of helplessness along with a completely useless, anxiety-producing activity. So, it’s the worst of all worlds.
