Insomnia - 27 Years - Vivid Dreams And Wake Up Every Hour (1 Month)

I have been suffering from insomnia for the past 2 months. It all came suddenly. I had shifted to a new country and had been living there for one month when this problem started. Initially, I stayed up extremely late- till early in the morning at 5 am and would fall asleep and wake up at 12 pm or later. But slowly, I ended up sleeping less and less. Nowadays, I can only sleep for 2-3 hours at most, and I end up waking every hour, and have extremely vivid dreams. I yawn throughout the day. When I do fall asleep during the day it is only for 30 mins or so, during which I have vivid dreams of me doing something or talking to someone. When I wake up I realise it was just a dream- but it was so like real life that its hard to distinguish it from reality. I also sometimes wake up drenched in sweat. I am so scared this might be fatal insomnia. What should I do? Try as I might, I cannot go off to sleep at night. I am so scared. Its as if I have lost the power to sleep. There is no history of fate insomnia in my family. But I have heard of a disease called sporadic fatal insomnia which doesn’t require a family history. I am 27 years old.
