Young and Doomed

I feel like this is my last day alive. I' exited for something, but I don't know what it is. It's like I'm here, waiting at the edge of my seat for nothing, and the worst part is that I know that I'm waiting for nothing. I feel an overwhelming sense of doom looming around the corner, and I can't imagine myself existing after I fall asleep in about two hours. It's 10:35 P.M. as of writing this and I know that I will soon be asleep, but I'm scared that I'm not gonna wake up or I'll just flat out disappear. My body can't handle another night of staying up past midnight, but I think if I don't go to sleep, I will reassure myself that I won't disappear today. No, I'm not thinking of ending my life, but I'm so scared I just won't see tomorrow by some misterious event.
