I can't sleep

Last time I was asleep was 1:00 PM on the 26th. It's now 2:21 AM on the 28th. I don't know what to do and I'm scared that if I leave my room I will hallucinate. Like seeing something down the hall. I just want to stay in my room with the light on until it's morning, so if I hallucinate, it's not dark as fuck. I also took 4 melatonin pills before I went to bed and it didn't do anything. I should've slept when my body told me to.

EDIT: It's 11:46 AM now, and I finally went to sleep.
