Psycho Possession

Have you ever been afraid of the dark? No? Well, I have, and it is not fun. For my entire life, I've been terrified about seeing creatures in the corners of my room, paranoid that a body would crawl out from underneath the bed or straining to hear the creak of the door moving when nobody's there. I moved away to college hoping that these familiar fears would leave me in a new setting, but they only followed me. At first, the sights and sounds intensified, and I did not know what to do. Soon after, I found that it is not all bad. I befriended and fell in love with a girl who lives across the dorm hall. At first her support was so comforting; we would go on long walks or hang out at each other's apartments and just talk. Why now has it gotten worse and I feel like I'm back to square one? Even after my brother moved in with me the following term, I felt secure with the familiarity, but I'm afraid this only helped for a while. The voices inside my head have only gotten worse, and now they want me to do things that I never thought I would. I tried killing myself, but I couldn't go through with it. Am I going crazy? I think I might be worse than the monsters.
