Run Away
I heard that anxiety is the result of being in a situation where you can neither fight nor flight, and this makes a lot of sense.
With this insight, preparation for feeling anxious, learn how to fight.
I don’t mean a physical fight is necessary, but maybe. Sometimes fighting is strategically preparing the battleground so there is a tactical advantage. Prepare for the immanent struggle.
If you can’t fight it, run away.
I don’t mean that figuratively. When you are feeling anxious, run.
