There was a period when I was having full-blown panic attacks pretty frequently and overstimulation was definitely a problem. I couldn't go into supermarkets. All the colors and jumble of confusing products on the shelves were too much for me to handle. Plus the flourescent lights upset me.

I spent a long time trying to hide my anxiety and panic because I thought it meant I was crazy. I also had claustrophobia. I was pregnant at the time, and I remember going in for a sonogram, and for the first time finding the courage to say I have claustrophobia and could you leave the door open?

The doctor said sure. She was completely blase about it. And my anxiety whooshed out of my body, providing instant and great relief. After that, I realized that confessing was no big deal, and that keeping the secret was doubling my panic. So that was a huge help.

I went to all kinds of other self help groups, and tried to address my problem in holistic ways. But what finally cured me was getting on blood pressure medication. I take a beta blocker which keeps my heart beating at a steady pace, and as wonderful side effect, I don't get panic attacks anymore. I guess it's hard to feel afraid when your heart rate isn't increasing! :)

Thanks for this informative and interesting piece.
