Hypnophobia and ffi

Hi guys. I'm 19. Insomnia started 1 month ago, which divided my life into before and after. I have very wave-like sleep dynamics. Sometimes I sleep steadily every day for a week, then I start sleeping again every other day. Today I slept a total of 2 hours. I'm afraid that after a week of sleep, insomnia has returned and it will never end. Let's start with the fact that I am very afraid of FFI. In addition to insomnia, I watch myself very closely. My gait, hand tremors and thinking. And it seems that anxiety disorder is really capable of imitating any symptoms. I feel my hands quickly getting tired, my fingers are shaking and I constantly observe this, before there was tingling all over my body. At the same time, I am able to do physical exercises, push-ups, swim. I recently visited a neurologist who did not find any abnormalities in me during the examination. I did not have an MRI, but ffi is not diagnosed that way. I want to believe that this is not it, because doctors' examinations do not calm me down. it seems that it is not yet time for serious symptoms to appear and they are not immediately visible. 6 years ago in my city there was a case of ffi. this does not apply to me, but for some reason I am very afraid that it was so close to me. I also suffer from hypnophobia. 5 years ago it appeared suddenly, but I learned to live with it. and now everything is getting out of control. I know that I can sleep because I slept all this week. but now I am simply afraid of it. I am afraid to be in a dream and see any dreams. I do not know what to do. it seems to me that this will never end and will become chronic. or I will die from ffi.
