Explanation

I guess that up until now I haven't really explained much about who I am, and what's been happening to me (in specific).

I'm 18. I'm graduating at the end of this school year. I live in a small town.
I became infected about three weeks ago when my brother told me about Marble Hornets.
I've lost about a week in time since, and I haven't slept.
I'm starting to see Mr. S. in ways and places that shouldn't be possible. He's in the movies, on TV, in my freaking mind.
And I've been seeing windows. I've already mentioned one (how lucky I am to have a forest in the back yard), but they've been cropping up everywhere. Just square holes  with that hellish field (not a meadow now that I think about it, those are too pleasant) inside it on walls, in the distance, one time in my bedroom door. And he's always standing in it.
I've read accounts here and there, but haven't had the time to learn nearly as much as I should.
Arkady's trying to kill him with blunt objects.
Setoth's trying to kill him with spells (I'd normally laugh at this, but it seems to be working to a certain extent)
Zero tried to kill him, and we all know how that turned out.

I need to know what I can do. I can't just sit here and wait for him to step out of the frame.
