Unable to sleep. Advise. thnx deepanshu!

I experienced sleep paralysis 15 days back, since then I am unable to sleep at night, do not turn of the light in night, unnecessarily push myself not to sleep, mind becomes too heavy still I do not sleep because I feel someone is around me, its watching me, if I will sleep it (sleep paralysis) will happen again. I have termed sleep paralysis as a ghost in my mind, so if I will sleep it will harm me. Recently this problem has started in day as well now I feel the same during day time as well, I feared dark and nights earlier, now I am unable to sleep in day as well. This is badly affecting my health- i believe my immune system is getting weaker, brain is loosing concentration, I am restless all the time- searching for sleep always but unable to sleep. Earlier to this sleep paralysis event I used to sleep alone in the entire house during night or day, I never feared anything. However I am unable to sleep alone in my own room while my family is in other room. Pls advise. Thnx Deepanshu
