I'm surprised "Angry" is not number one. It is for me and always will be.
Ricky touched upon a good point in post #24. I resent that kids, my nephews, my friends' children, etc.,...cannot experience the carefree life as a child and teen growing up in the US that I did.
September 11, 2001 essentially was the crowning moment of disillusionment, for me, that had begun with the taking of the 53 hostages in 1979 with the fall of Iran, where I lost a certain feeling of security and naivete, that I will never have again.
