How do I start this..

I was diagnosed with Astraphobia when I was 7 years old. My first signs were that I was always watching the weather channel for upcoming thunderstorms and I was getting really anxious and sometimes I was vomiting when there was a thunderstorm in our town. So my parents took me to a psychologist for children and that's when they diagnosed me with Astraphobia. I have also read that this is an abnormal fear? I thought it was pretty common...

Anyway... Sometimes I panic so much that I eventually pass out on the floor and it's difficult to wake me up. I developed gastric catarrh because of my fear and I know that my gastric catarrh will get even worse this summer because they have said that there are gonna be more thunderstorms this year than last year.

I haven't really been hit by lightning before, but there was two times that I got an electric shock from a lightning. First time was when I was around 11 years old; I was gonna turn off our lamp in the living room in our apartment and the lightning struck right outside our apartment building and I got a huge electric shock.

Second time was when I was living in Norway, I was around 14-15 years old. I was standing in our hall talking to my mother over the phone (a phone with a cord) and the lightning struck in the power line outside our house and I got another huge electric shock. So after those two times, I refuse to be near a socket whenever there's a thunderstorm.

I get paralyzed when there's a thunderstorm. I read that some people use the restroom a lot, but I don't. I get paralyzed and I refuse to leave my spot. I usually cover up my window in my room when there's a thunderstorm and I get really paranoid, anxious and stressed.

This is something I want to "cure". I don't want to be afraid anymore. Do you guys have any good advice what I can do to calm down during a thunderstorm? I've tried listening to music through my iPod and it works a little bit, but is there anything else I can do to be less scared?
