I think Lil said it just right... you're reacting. Tragedy struck close to home and it is certainly unnerving. There is a girl I know of, that I've never met, that is almost certainly about to lose a battle with cancer. She's a friend of a friend that I know almost nothing about and yet thinking about her situation causes tears to well up.

I think talking about it is a good way to help deal with what you're feeling and I hope putting it out in the open here will help you see you're not over-reacting... and you're not alone.
