This is barely related to science but how do I stop fanticizing about the past everytime I try reading a book I always think about my glory days from years ago, in the past 8 hours I finished only 30 pages when I literally did nothing other than "read", no 4chan or other websites. I do this regardless if I'm reading or not, and its a bad habit because it makes me think the present is better than it actually is, when in reality it's complete shit. This has been going on for years, is this what adhd meds are for? Can someone recommend me something to take?
