How awful! Death can be a somewhat scary thing, especially if it's a peer. My whole life I spent attending funerals of my family, so I was accustomed to losing people, both unexpectedly and as a result of a long illness. My "comfort" with death changed dramatically when, at the age of 20, I heard on the news that a high school classmate who was in a trench working construction in our home town, was buried to death as the trench collapsed. Soon after that, one year out of college, a very close friend of mine committed suicide. The whole "death" concept changed when it was someone who I felt could easily be me.
At times, I am not afraid of death; and other times I am. But in either case I feel comfort in knowing that these types of things pull life into perspective for me, and I try to live knowing that I may not see someone again. I do believe, however, that "death" is not a bad thing, but rather a passage to something more rewarding.
Until then Kristi, just try to live your life, and yes, be careful, but not fearful, as Cathy stated. There is a difference.
