nobody knows where they might end up

It was about 1:45 when I got home, and then I went to sleep but didn't really sleep. I kept waking up. Finally, around 4 AM I threw up several times. Then I started hearing this buzzing hum that got stronger and stronger as I weakly tried leaving the bathroom, and I vaguely remember crashing into the wall, not so much the action of it but the pain that I felt afterward on my forehead. I also felt pain on my lip, but I don't know how that happened.

Then I passed out and woke up on the floor of the hallway, feeling slightly better. The buzzing, at least, was gone. I went to sleep and I've spent the entirety of the day watching Grey's Season One.

I have this fear that I'm going to die, and I've wasted my life.
