Good question!

I find it helpful to try Not to focus on the anxiety/fear.

Distractions can be helpful, computer games, listening to music, going for a walk, doing something different to take the mind off it.

Relaxation- buy a tape and practice it every day, difficult to do when you feel like running away.

Breathing- for when the panic gets really bad. Yes I have breathed into a paper bag for 10 minutes, or you can cup your hands over your mouth and concentrate on slowing it down.

Take care.
