Hi, Thursdy. Yep, to us is sounds like an anxiety attack to say the least, but that's because many of us had/have them. However, none of us are doctors so we can't diagnose, espcially with limited information. You're best bet would be to talk to your doctor about what happened. Once he figures out what it may have been, he'll know better on how to proceed.
This is a supportive, caring website where we support each other once you have a diagnosis. We will also encourage you to do that. So... I'm strongly encouraging you to see your doctor.
