Fruitflies and fours hours of sleep...

My sleep has been really erratic lately. I fall asleep fine, but I wake up usually 3 hours later and can't fall back to sleep.
Being a giant dork, I went to bed at 9 last night and was inevitably up again by 12. I got up for a while and then went back to bed and fell asleep for an hour or so around 5.

My dreams lately have been super messed up. On friday I dreamed that I overdosed and when I woke up I was convinced it actually happened. Weirder things have happened. I didn't know whether I should call 911 or just go back to sleep and let what be, be.
Last night a bunch of people were brutally murdered in my dream, and then in the end it turned out to be a sick joke but I wasn't laughing.
Having dreams would be one thing but when they affect the rest of my day I start to get concerned. It's like my thoughts are filled with the morbid images and thoughts until I go to bed to dream or new disturbing images to fill my waking hours.

On top of the dreams, since Friday I have been having overwhelming urges to hurt myself. I was walking down the street and I had the urge to jump infront of a car. I was doing laundry in my basement and I wanted to throw myself down the stairs. I want to break bones, see blood, feel pain. I don't know where this is coming from. Life has been pretty stable other than sleep. I cut, but I never do any of those other things. I stayed in my house all weekend to avoid any situations where I might conveniently walk into traffic. I don't know if I would actually do it but that uncertainty is very alarming.
