I used to be an avid reader, but years of high school and depression completely ruined that. I haven’t been able to complete a novel since senior year six years ago. It’s frustrating to me and I want to know how I can overcome my lack of focus and anxiety. I’ve heard I’m not alone when it comes to this sort of thing at least.
E: I wasn’t expecting so many replies. Thank you, all of you, for the ideas.
You most likely don’t have as much free time on your hands. That is a major reason for this. You can start with smaller books of interest to get the feeling of completion.
