I may have developed pseudoinsomnia. My sleep is half-awake sleep and in 90-minutes-each fragments. It started one evening, when I tried to incorporate an unincorporable thought into sleep. That thought is now perpetually incorporating on its own; it's like a 24/7, autonomous background process.
I went to a sleep specialist and a psychiatrist for help, but I personally didn't find them helpful. I am now desperate.
I have tried treating myself with herbal and sleep restriction, and I am on eight sleep medications, with two strong ones and two that have been found to aid in pseudoinsomnia. I don't find any of these to be effective. I'm now eyeing ECT and am curious to how it will affect me. There is no consensus on its mechanism of work yet, but I know I have a dulled default mode network that is now hijacked and altered by this persisting thought; and somehow ECT can delete these alterations if it can.
