I let it get to me today. I was commuting home via BART and while under the Bay the train stopped..... for a long time. The driver announced that there was something in the "tube" in his way which would not let him get to the other side. We eventually rode the train back to the original side of the Bay. They closed down one of the "tubes" and had both directions' trains utilize one tube, causing massive delays and slow trips through the tunnels. On the second, extremely slow, trip through the tunnel under the Bay (full of freezing cold water and no air) I was pretending to be relaxed, but was anxious and overwhelmed. Finally we made it to the other side and I just left the BART, even though I wasn't at my stop yet. I took a longer bus ride home, but just didn't want to be in there anymore. I know, I panicked, but I was nervous. Stupid, stupid terrorism.
