I got my hyperthiroidism confirmed. I have treatment and Ive been sent to a psychiatrist for my sleep problems. But not I have other thoughts. What if I have some sort of mental illness that will make me lose my mind step by step. I mean,I have this unfamiliar feeling that no one,nothing around me is familiar,not even me when I look in the mirror.It scares me to death. I know who Im talking to,but I feel so detached and its scary,it feels like im losing it,like Im going to die. Its very unpleasant. I think my DP/DR are caused by my lack of sleep. For the last 2 months my average hours of sleep are 2-3 per night,sometimes more,sometimes none. I feel exhausted and I just want to sleep. I have these dying thoughts,I feel like it would be better if I just die. But I dont want to. I feel like the world is a scary place because I might lose it in the middle of the street or something. Everyone told me that I cannot be schizofrenic,because that is my biggest fear. Please,people who experienced DP/DR,answer me: does anyone feels like nothing in familiar,not even people around you? Its scary. Does anyone else feels very disoriented? Does anyone else feels like they are on the edge of losing it,of dying or of going crazy? Also,I have random moments in the day where my DP/DR are more intense than usual,it feels like im in another dimension. Do I sound crazy?
