Let the record show that I enthusiastically believe that 9/11 was cool. It was like having a front row seat to one of the greatest events in American history. My parents got to live through the Great Depression, the Dust Bowl, WWII, Korea, Vietnam, the 50's, the 60's, and the Kennedy assassinations... so I'm pretty sure that I've got some catching up to do as far as living in interesting times goes. You may not appreciate struggles, but I absolutely revere them. They're not to be bemoaned, they're to be cherished.
Struggles, and how we rise to overcome them are one of the few things that make life worth living and our ancestors worth remembering. Happiness and bliss may make for a noble quest, but it's the struggles that allow you to appreciate them.
So have your moments of horror and grieving, and then file them away in your repository of hallowed memories... not because you had to endure them, but because you got to.
