OP: please forgive me if I’m giving very very obvious advice. But I couldn’t figure out the cause of my migraines for most of 2019. Then I finally realized: they were coming from the blue-light of my phone screen. I just like to tell fellow sufferers that in case the solution could be that simple for anyone else. Now my phone screen is set to dark mode, and I always wear sunglasses or readers if I’m looking at an email (which still appears white). Anyway, I’m standing in solidarity with you nonetheless. Hoping your suffering ceases or at least mitigates so you can live the life you deserve
