Just for note: I'm a twenty-five year old male. I have a history of depression and suicidal ideation, which has presisted for at least four years. There is a history of mental disorders in my family, with my grandmother and mother both suffering from anxiety disorders, my father being bipolar, and a few members of my family who are autistic or psychotic. Recently, for the past year and a half, I have been having strange experiences. When I sleep, I dream of the world ending. Last night was the stangest of them. I was completely alone in the world, existing in a painfully bright room by myself. During the day, I would put on a biohazard suit and search for water in a barren, grey wasteland with heavy clouds that blocked out the sky. I would have to return to my room when night fell, otherwise I would be crushed by the blackness that night brought. But even sleep could not bring me comfort, as there was no way to extinguish the white light in my chamber. But my problems do not rest purely with my sleep. I have been having periods in which I feel that I assume a different guise; that a madman has entered my body. During these periods, I am prone to breaking things, to screaming obscenities, and boughts of self-harm. I punch walls, I throw things, I shatter glasses. I have a hard time remembering these periods after I calm down. I also have distinct impressions that people are listening to me in my apartment, that people are plotting to kill me, or that a demon has entered my head and is directing my actions. I occasionally hear voices calling my name, or see shapes moving in my perpheral vision. When this first started, they were simply shapes; but as this has progressed, more and more detail is becoming apparant. These "visitors" look human. I know that these are not rational thoughts or beliefs; and yet I have them, regardless. Most worrysome, I am now having perceptions that time is skipping, much like a record on a faulty record player. There are simply brief periods of time that I cannot account for. This is affecting my job performance. I have been counseled three times over the past month over my work-related demeanor. My boss attributes it to stress and I've been given a few days off to "calm down." But I am worried that I am losing my mind. I feel as if my sense of self has been stripped away, laid bare, and that another man that I cannot recognize is standing in my place. I accidentally referred to me as "we" the other day, which drew some strange looks. I have no idea what's happening to me. Quite frankly, I'm scarred shitless. Does anybody else have these, or similar delusions? Or have an advice?
