I can relate. Once I was on a date and I had to excuse myself to the bathroom to throw up from anxiety. I didn't know anything about panic attacks as a condition and instead just blamed myself for being shy. Man, if only I had gone to a doctor- which you can do ! They can give you a script for a medication such as Ativan which will stop panic in its tracks. It takes some learning to get the right amount at the right time. Too much and you'll be a sleepy and dull social companion. Get it just right and you can make it through those awkward moments and hopefully on to a nice relationship.

Good luck!
