Jenn1fer82,
That sounds dreadful, how really awful for you.
I think you need to contact a doctor about this as soon as you can. Is there someone you can ring?

What stratergies do you use to cope with these awful panic attacks?
I find that my breathing goes completely to pot, so I have to cup my hands over my mouth for at least 10 minutes.(a paper bag can be used instead if you prefer). This usually works well and stops me being sick!
I suggest that you be aware of your breathing and notice when your body starts to tense up, so that you can do something about it quicker.

Thinking of you.
