A Friend of Mine Just Ped Away? This is the first time someone ever this close I knew really did die?

He died on November 26, 2008 at 1 AM of Ewing Sarcoma. I remember that I called his dad's cell (the only phone number in the directory) and I left a very nice message saying something like "Hey man this is your friend, I want to wish you good luck to get through this cancer and I'm letting you know that I'm thinking of you, and if this is my last message before you die, I want to say farewell to you. I love you bro. Bye." But I did say my name and his name I just don't want to give it away on here. I left him a voice message either the night before he died or 2 nights before he died. I felt bad because I don't know if he ever got my message. I hope his dad said the message to him before he died. When the principle announced it, he was chocked up. I feel more moody than sad. Is this normal? And do you think that was the right thing to send him a nice message?
