I get this wierd and sad feeling inside myself?

I'm 15 and I grew up watching the Jackass series, CKY etc, and just the recent death of Ryan Dunn has made me watched Jackass 3D, I watched the entire thing until the end where the song 'Memories' plays, it made me tear up and I thought to myself, "I have so much aquaintences but not one real BEST friend, knowing that I can be completely stupid and immature with, and to grow up remembering them all', has anyone else felt this way before?
