Chronic brain fog, eye focus problems

For roughly 6 months now, I've been struggling with a very chronic brain fog/ inability to think clearly. The condition came on so strong that I became incredibly disoriented, confused, and even depersonalized. I was feeling so much dread and despair due to feeling like I wasn't myself, and having to wrestle with mental unclarity all day. It is hard to describe the condition, but it is as though I have little to no energy behind my thinking, so thoughts go by very quickly, and make concentration nearly impossible. In the past month or so, I have been able to achieve a bit better handle on what's going on and am less confused, although the brain fog is still quite severe.
The brain fog is coupled with a persistent eye condition in which my eyes go in and out of focus all day long. I have 20/20 vision, but the focusing system/ focusing muscle in my eyes will cause whatever I'm focusing on to momentarily blur and refocus throughout the day. This has been going on longer than the brain fog, but has gotten much worse lately, and it just feels like there is a link between them, although I don't know for sure.
Has anyone heard of anything like this??? I went to neurology and they basically just ruled out anything life-threatening and sent me on my way without a brain scan. I've gone to a few opthalmology appointments and they haven't been very enlightening either, as they have been about as confused as me about why my eyes are doing this. My next appointment will be with neuro-opthalmology
The last thing may be the weirdest part, but my brain fog/ eyes have often felt severely worse after m-bation/ wet dreams. This brings about insomnia, and causes my whole body to tense up and become tight. Is this psychosomatic? I know this is strange, but it's part of this weird, confusing puzzle. This whole thing has just been devastating and I'm desperate to find some answers. Any insight would be greatly appreciated, thank you!

Curious if you can pinpoint a certain event or illness that triggered what you are describing. I went through 3 years of CFS after a virus 8 years ago, and the vision thing was all part of it. I ended up taking adderall or vyvanse to help me, but it did eventually resolve. I had a major surgery a month ago, and was put on some heavy antiobiotics. I stopped those recently, but have the same feelings now that I did when I came down with CFS earlier. Scares the heck out of me of course.

Yes I get that- plus worsening eyesight- I even went completely blind for around 45 seconds or so (Was lighting a cigarette at the time, and everything went black and i couldn't even see the flame)- seemed like an eternity- Eye Doc said it was nothing- said hisw sister-in-law has that happen- I dunno- i never pursued it further after that- I get the brain fog bad too- have had it for 30 years now- and exhaustion too- One doc 'thinks it might be' chronic fatigue- another 'thinks is might be fibromyalgia' , and other doc said some other type of myalgia- i don't know what it is but it has disabled me- I've been checking into the possibility that it is caused by one of the herpes viruses- HVV-6, which apparently nearly 100% of the population has- but i nsoem folks, it suppsoedly reactivates later in life- and might be the cause of CFS-
