So tired

I have not slept in 3 days.
I have tried to sleep, but I just haven't been able to, I just lay there, awake, all night.
The thing in my spare room keeps making noises, banging on the walls and sometimes screaming, I wish she'd just shut up.
He was in my room last night. Sitting in the chair that goes with my desk, having a look. I tried to pretend that I was asleep, act like I hadn't seen him. He was there for four hours.
I haven't eaten much these past days either, I just keep forgetting.
I've been forgetting a lot recently, I was watching a film earlier, but at the end I had forgotten what it was about, I couldn't even tell you what it was called.

I am just so tired.
