Well, it's hard to be sympathetic in this situation for me, because I know what it's like to loose a friend, even one that you didn't know well. It hurts, it really does. You have my empathy.
A classmate of mine was gunned down this year by a kid from the rival high school (Arsenal Tech). He was the star basketball player for our team (Emmerich Manual) and I knew him a little bit because he played on the football team with me for a couple of weeks. Even though I didn't know him well, it was still sad to loose him. We lost that year in conference as well, because he wasn't there.
I know it hurts, even if it's just a little, you can pull through this, just keep your head up, and keep on going on.
