Some people are always afraid of having a heart attack, some are afraid of seizures, I am afraid of
throwing up. These are all things that are uncontrollable, and that's what makes them scary to us. I know that these pieces of advice are probably not medically sound, but this is what works for me... Don't get more than 7 hours sleep, 6.5 is my max, and 5 is my minimum. When I am too rested, I have a buildup of energy and I feel so much more anxious. Second, exercise.
