Sleep Who?

For the past weekish, I have been having trouble going to sleep. Tonight is no different. The reason is, I'm afraid to. I keep having these bad feelings that something is going to happen to me if I fall asleep. I feel like if I sleep I might die in my sleep and never have another chance to make everything in my life right. I keep telling myself that I can die being awake too so it really doesn't matter. But I still am afraid of falling asleep. I get so tired every night waiting for myself to just give up and give in to sleep. Sometimes I can't fall asleep until like five am. For me, that is crazy late to stay up. I used to go to sleep around nine or ten, eleven was pushing it. Tonight is a particularly bad night because my fear won't subside even for a second. I was texting a friend to try and keep my mind off of it, but now he has gone to sleep and I am left all alone in the dark, afraid to sleep, to look outside, to be alone... I can't keep living like this. Something's gotta give, right? If this gets any worse, I will never sleep again... I don't know what to do.
