Is it wrong not to be scared of death?

I am 17 years old, I am just an average teenager, well at least people think I am. Ever since I was little I have gone through so much stuff. (Just like everyone else.) I prefer to keep the events private. One thing that has me confused as an outcome of all those things, is that it has left me unafraid of death. I don't care if I die today, everyone alive is gonna die anyway. It's not something I worry about, you know? And I know it's weird to be thinking like that, and while I may be somewhat depressed, I don't believe that is the cause of how I view death. Can someone please help me? I know it's not healthy to be extremely afraid of death, but I just don't fear it at all. I mean, I will help myself if I am in peril but at the same time, if it happens, it happens I say. I just find it odd.
