Anxieties of anxiety attacks

My throat feels like it's closing up... I feel like I have to keep taking deep breaths to get air in my lungs... my ears keep popping.

Great, now my body temperature is changing and I feel like I have to pee all the time... my hands are either clammy or sweaty... my head is pounding... and I've got muscles twitching in places that are just odd and funky.

WTF? All I'm doing is working! Maybe work makes me anxious. Or maybe I'm anxious to get home and get high...
