I can only tell you, what helped me, I finally had enough and said I'll just fight through it and live my life rather then worrying about my symptoms, i started working out again, being active, i believe forcing my self to get get active helped me, exercise releases dopamine makes you start feeling better which i was lacking a lot of, after some time i noticed i was feeling a lot better

i had similar issues couldn't read more then a few sentences, i couldnt search for stuff, if I was looking for a shirt in a closet or anything really couldnt do it for very long,

but now I am able to read stuff and what not

also maybe try and read outdoors sitting on the porch or something, fresh air is always good
