Sad to see you leave, YSR. You'll be missed.
Aww... I'm really sorry, Khold. That's got to be so hard. While I don't know how much help I can be, I can and will at least pray for you and your friend's family. I've never had someone really close to me die, but I can only imagine how terribly difficult it would be.
Um, no offense, BLF, but I don't think your advice is a very good idea. This is a really tough time for Khold, as it would be to anyone else in this situation.
My best advice is that after the initial shock, you give yourself time to mourn. In extremely hard times, giving yourself time to grieve allows you to release the pain, so that, in time, you'll be able to heal. Holding in the pain and trying to "move on" too fast only stifles it, and it will remain bottled up, and you'll possibly never be able to function the same. While it may take a really long time to heal, and/or you may never heal completely, it will definitely help. Don't be afraid to cry or talk about it if you need to. Try to function as best you can at school and other tasks in your life, but don't try to suppress your pain, though; give yourself time so you can release the pain somehow. I also suggest prayer (religious or non-religious, if one's in a time of crisis, try it and see what it does) and surrounding yourself with people who can help and comfort you through this time.
I don't know how good my advice is, but I've found that to be effective when I've gone through tough times. I hope this will help, and, as I said, I'll be praying for you.
And wow, this has sure gone off topic with those kitties, guys.
