Why do I always experience this when I happen to be alone?

I was just at the bank running an errand, when my puson began to hurt. I had been doing fine the whole day. Why is it that just when I went out, it started? I started feeling dizzy and broke into a cold sweat. The dizziness turned to nausea. I made it through the line and headed straight for home. I was supposed to have dinner with a friend but at this point I was glad I made it home ok.

Excruciating pain coupled with dizziness. This happens to me every once in a while when I get my period.

I just have to weather this out alone.
