I've had pretty severe anxiety for many years and I have to say people have recommended many things I can think of. Besides drugs and therapy though the thing that helps me excercise. Seriously. Sitting around makes the crap compound until my mind often would just freak me into having an anxiety attack. When I felt anxious I would go out and run or excercise. The brain releases dopamine when you excercise and makes you feel better quite quickly. The other thing is. No one has ever died from an anxiety attack. Seriously no one has. They suck but they aren't life-threatening and they get over fairly quickly. You're going to survive. Keep telling yourself that.
