Welcome....I don't have a mTBI but my daughter does so I can relate to what you are stating as your symptoms. She pretty much had all your symptoms except that she could watch movies on a small computer screen. (This made sense to the eye doctor)

She is 2.5 yrs out. However she is improving cognitively month by month--tests scores are increasing. She still can not do vestibular or eye therapy yet

I know more people will reply but as usual you might want to begin Mark in Idaho's vitamin regime. There is a sticky and most people write that it has helped them.

What has helped her...
acupuncture really helped with her headaches,

osteopath helped with the pressure in he head,

wearing sunglasses and hat--24/7,

finding the correct dosage for her depression,

sleep meds,

cognitive behavioral therapy for help with accepting the position that she is in

prism glasses with a dk blue tint (most people want to eliminate the blue but this is the color that soothes her eyes.

This will get better

My best,
