There’s a lot of good advice here, but I will add that some people are just slower readers, and that’s perfectly okay. I’m a fairly fast reader. My brother is a very slow reader. He still graduated college with an English degree and then went to law school. He reads all the time (more for work than pleasure now) and is a beautiful writer, but he’s still a slow reader. And that’s fine, he just has to plan for it.
It’s absolutely not weird. Or at least you’re not alone in you’re weirdness. When my father was diagnosed with brain cancer and had a surgery that left him significantly impaired, I was in a fog. The only thing that sounded decent to read was Harry Potter, so my 35 year old self re-read all of the books. It felt like a lifeline.
