I don't think that you're unusual at all.
September 11 holds a very special place in my memory. I didn't lose any loved ones, nor have I ever even been to New York. In my opinion, it felt as though all of our emotional walls fell down in those days surrounding the tragedy. We were one, we realized our humanity, our fragility. Terrifying. That humanity did give us something wonderful that I wish we could get back into our daily lives: sensitivity for others. We really cared.
It didn't matter if we were 20 or 20,000 miles away from the tragedies. People from all the world were travelling on those airplanes. I cannot imagine the horror that they felt. It scares the hell out of me when I imagine it!! I honestly don't think that will ever go away from my life.
I keep control of my blown up emotions by choosing not think about the tragedy too often. Otherwise, those intense emotions can grow a life of their own in my world pretty quickly. That's just the way I am..very emotional. I therefore feel the need to control how often I give myself access to drama. Sounds kind of pathetic, as I read this...But, that's just the way it is for me. Maybe you should try that??

Gentle hugs
