Find shorter books to read that can hold your attention!!! You can also try to read things online rather than having a physical book in your hands. I find when I have a physical book and I can SEEE how big it is I get intimidated and don’t want to finish it. Reading online lets u just kinda read however much without really knowing how long the book is
I’m in the same boat! I also have ADHD and I’ve also wanted to read a lot, but I’ve barely read anything. Something that’s helped a little is listening to audiobooks, so when I do some stuff like laundry or driving, I can also be listening/reading too. Other than that, sometimes I literally have to force myself to read instead of bed rot on my phone
