Good morning! As you can see, I too am awake! It's a common problem at this time of life. There are plenty of threads on this forum to look at.
For me, this has been going on for 3 years. I have found wearing solar shield wraparound sunglasses 2 hours before going to bed has made a significant difference in helping me get to sleep. They cut out blue light from TVs, PCs etc. Not a glamorous look, but very restful for your eyes. My chiropractor recommended them. I found them on Amazon and they cost a mere £20 including p&p. Doesn't help with wakefulness in the night though.
I am up tonight though, as I have a virus and asthma has decided to join in. Not much fun.
