I was a really strong reader as a kid but when sz hit I couldn’t read to save my life. This lasted for several years. Eventually on some meds I was able to read finally but I still zoned out a bit. Now it’s much much better.
Depending on what your exact trouble is there are a lot of alternatives to reading now if you find you’re interested in something but actual reading is tough. Audiobooks can be great. The library here has an ok selection. I have found that I like listening to lectures or presentations instead of reading sometimes. YouTube is full of good content that is recorded fairly well. Someone started a thread on open source courses earlier and I have really enjoyed those.
If you have an Apple device you can access iTunesU and stream or download quite a bit of content for free.
Not sure if any of this helps at all. I have found that a lot of the things our brains will and won’t do change often and can’t really be reasoned with. Sometimes it changes in its own. Sometimes it just evolves. When I went into remission I found that so many things I thought I we tuning out had been lodged in my brain somewhere. Not everything of course but when I felt so far removed all this stuff around me went in and I didn’t know.
