I don't feel like i'm falling asleep at night (for 1 mo).perhaps just getting microsleeps.i can't fall asleep no matter how tired i am.fatal insomnia?

Unlikely: There are medical causes for insomnia which must be first ruled out for proper diagnosis and guidance. See your pcp for evaluation. Bring list of any meds you take (prescribed/OTC/supplements), use of alcohol/drugs/tobacco/caffeine, current stresses. Start a sleep log. See: https://sleepfoundation.org/insomnia/content/what-causes-insomnia and https://sleepfoundation.org/sleep-diary/SleepDiaryv6.pdf I hope this helps. Best wishes.
