don't get frustrated this aint disorder this is just human behaviour. most people think concentration or focus means especially while reading they connect it with not having thought about anything and your mind becoming empty and that is not going to happen. so try this, pick a book, like an interesting one and read it but when you read it try to engage with it. like ask question, ask the author, do your own research, try to imagine the things but never go out of the topic and then try to think about that book all day by talking about it to others and just by being creative about it. so doing all this will let you understand that focusing or concentration is not about silencing your brain from generating thoughts (because thats what everyones brain does) rather using all brain power to one task.
