I am like you though, I do not like to fly.
I will admit here on CB that I am claustrophobic. Have been for along time. For me flying is like being trapped in a tube, and being told to not move for several hours. Small planes are the worst for me, I am also not a small dude which only compounds this experience for me.
I have always preferred driving to flying, though my wife has tried to get me to go to Europe for 10+ years now and I just cant come to grips with the thought of being in a plane that long. I know there are over the counter drugs but none have worked so far for me.
Anyway, I truly hope you are doing better and that they brain will work itself out overtime.
