A lot of people have never had panic attacks, and if you have never had one, it is extremely difficult to understand them. Something happens inside my mind that I have never been able to describe. I have often tried to explain it as my thoughts get physically bloated, somehow. See, that makes no sense.
I was listening to Radiolab, and they were discussing time. It was fascinating. To begin and close the program they play excerpts from Beethoven's ninth symphony stretched to 24 hours. At first I thought it was relaxing, just these beautiful long notes, but then the music starts building. You are waiting for the climax, waiting, waiting. Time slows way down while you are waiting for the music to just go over the top of the mountain. The anticipation kills you. The music builds and almost physically gets fatter. You just need the music to climax so that you can relax again and enjoy the notes. But it takes forever.
This is sorta what my panic attacks feel like.
