I really feel your situation. I had this problem and still have it (Just a little bit)
Things I would suggest you should do.
>Tell your parents about your problem, they will understand.
>Keep a light on, a lamp is the best thing to do.
>Have some DVD of an old TV show playing (Something like Andy Griffith or the Honeymooner.)
>You can watch it, or stare at the screen with your eyes closed, it helps.
Edit: Also, I didn't look, but who ever posted that picture of the Chick from the exorcist (Scary Maze Girl) really needs to snip it out. You don't understand this situation and how critical it is.
