yeah, that was totally me
Senior year of highschool, a combination of my internet addiction, ADHD, and anxiety issues finally made it so I couldn't read a single page without my mind wandering and taking like 5 minutes to turn the page
The best advice I can give is to have an isolated reading space, away from any digital devices or distractions. Don't even leave your phone in your pocket, and set up a dedicated reading chair in another room or something.
Although what actually helped me was finding a book that really captured my interest and reminded me what I used to love about reading, but that's obviously super personalized and idk if I could direct you there. Maybe re-reading a childhood favorite?
Actually, I recently started reading Midnight Sun (Twilight from Edward's perspective, just came out a few months ago) and I find myself reading for hours and much more pages than books I otherwise enjoyed like American Psycho or 2001: A Space Odyssey. For me, that was the perfect mix of something old/something new.
I also started a New Year's resolution to read 100 pages a week (so I can actually get through this reading list), and I try to read 20 pages a day, with 2 days built in for breaks/lapses. 20 pages isnt a lot, maybe like 30 minutes of reading, but it really adds up over the weeks, so you can start to get invested in stories and it won't be so much harder to keep reading.
