Hello and welcome to the Planet MrShadow, that's quite a introduction!
Glad things are improving for you, but what a hellish nightmare you've gone through. I can relate, albeit it in a very modest way, as i have ASD plus Usher Syndrome (genectic hearing & vision disorder), but your problems put mine in perspective! My sister's bf has the severest form of epilepsy, he too has tried all kinds of medications including CBD.
I hope things work out for you, and good luck with your own vape journey.
