PilotSimone,
Welcome to Avalon!
I have suffered from anxiety and insomnia most of my adult life. In times
of extraordinary stress, I would experience sleep paralysis and night terrors
to boot. As my mother, maternal grandmother and uncle all have suffered
from similar symptoms their whole lives, I suspect there is a genetic flaw at work that causes a chemical imbalance.
I suggest looking into the Ultramind Solution by Dr Mark Hyman.
It has helped me a great deal. I am still experiencing symptoms,
but they are under control and I expect them to continue to abate
as my body adjusts to some recent significant changes I have made to diet and medication.
Some of the others here have already made some good suggestions regarding other angles that may be helpful to you. I do think that I have been targeted by the dark forces at times, and the angels are the only reason I am still here. I practically have a direct line to Archangel Michael!

Ask them for help as often as you feel the need.
My heart goes out to you and your son.
Sincerely,
FIIISH
