Good luck to you.
I've had insomnia since I was a teenager (20+ years) and I've tried it all.
I've done a sleep study, seen neurologists, done cognitive based therapy, improved my sleep hygiene and am currently the patient of a sleep medicine specialist where I've tried basically every sleep medication known (none of them help much).
Personally, I didn't find the cognitive based therapy helpful, but maybe I wasn't being open to it or it wasn't the right fit.
I don't have any physical problems like sleep apnea, but my sleep study showed I have an a very high number of arousals while sleeping. Also, my sleep medicine doc said she believes I'm a highly sensitive person, which is contributing to my insomnia.
I know it's not the question you asked, but I guess I'm just commiserating with a fellow insomniac. It's of course worse right now and I'm really bored.
I hope it works for you. Is this type of counseling considered essential? I'm curious if you can schedule in person appointments right now or not.
