Death threats from roommate

So I’m in college and got a random roommate since I am a freshman. This girl never sleeps in the room because she sleeps with her boyfriend but she always has her nightlight on. This nightlight does not turn off unless you unplug it. I cannot sleep with it on so I often take it out of the wall for the night and plug it back in in the morning but she has a class before I wake up so she sees it unplugged but I didn’t think it would be a big deal since she doesn’t sleep there. But I was wrong. When I went to unplug the light once again last night I found a note underneath it from her.

I ended up not sleeping last night and staying out in the library because I’m kind of scared of her now 😟
