I can't stop. I feel that another person lives inside me, with me. I know it doesn't exist, but I can't stop talking with it. It's like an imaginary friend who lives into my mind. I'm forced to tell him all my thoughts, my considerations, my observations. I must speak with him, because though I decided to stop, I would restart almost immediately, because I would forget to stop. When I talk with me, I talk in a low voice, so nobody notices that I do it, but I'm really desperate.
