Should I let my fear hold me back from doing what I want to do in life?

Im 24 and I've been wanting to join the military for a good 3 or 4 years now. Its on my mind everyday. I dont want to join just the regular military though. What i want to do is more risky and dangerous. The training alone could kill you. That's what I love about it though

I don't consider myself christian because I'm not very into it but I've always believed there is a God. Too many people say they are when it's obvious they aren't. One of my biggest fears though is going to hell when I die. I'm pretty sure I would if I died right now because I don't think I'm saved and that's what's holding me back. Im not scared of dying. I'm scared of what happens to me after. I got a friend at work who was in Iraq in 2004-8 and he says shouldn't worry about that. Thinks I'd do great in the military and I shouldn't let that fear hold me back.

I just really don't know what I should do. I really don't want to do anything else
