have you tried ice? Get a few ice cubes and hold them in your hand. If you still feel out of control, try sticking your face in a bowl of ice water. I have done that when I have become hysterically upset. It's one of the things my t has coached me to do over the phone.

Do you have any funny movies that you could watch? Do you have any funny TV shows that you can watch to get your mind into a different place for awhile?
