Just Passed Out

I just had a full blown panic attack and blacked out for a second falling on the floor. Good thing my fiance was here to take care of me, or it probably would have been worse. What brought it on? I have no idea. I was opening a can of stuffed grape leaves, and boom it hit me. I did have a conference call with work today and starting work next Monday... that's probably why I had it. I'm tired and need to lay down... just wanted to document the panic attack for future reference. I will update you further tomorrow.
