Welcome to the board, Nala!
14Fuel, I am so sorry to hear this, that is really sad and I hate hearing about things like this. I know the pain that someone goes through when they are grieving, someone close to me lost a very special person in their life to suicide. Even though I didn't go through the pain myself, seeing someone grieiving and depressed over it, words can't explain how much pain you go through yourself becacuse of that.
Anyway, I am very sorry to hear that.
Try and be there for his family as much as you can, and what you said about appreciating the ones around you, your loved ones, is very true, and we shouldn't take anything for granted, because you never know when it may end.
