Unknown neurological cause (help)

21 year old male have been bedridden with neurological issues with unknown cause. No triggers or change that I can think of. Came fast out of nowhere and now just my new normal

Got severe head pressure and head burning along with vision issues (halos, starbursts, everything looking too bright)

Severe brain fog and dissociation. Brain completely blank like brain dead

All of these are 24/7 for 18 months straight no break

Normal Brain CT
Normal CTA
Normal MRI
Normal EEG
Normal Bloodwork
B12, CRP, CBC, Chem 9, a1c, Lyte, creatinine, ALT
Normal TSH and PTH
Serology-Lyme IgG/IgM NEGATIVE
Normal ANA,ENA and Thyroid Antibodies
Negative EBV panel
Normal Urinalysis
Urine Drug All Negative
Urine heavy metals 24hr all normal
Autoimmune encephalitis/Paraneoplastic Blood+ CSF Negative

Doxycycline for 3 weeks did not help.
migraine meds didn’t help. Corticosteroids provided some temporary relief (not sure why)

I don’t have positional changes either.

Lumbar Puncture Results ( all normal with slightly high protein so far)
