IMO, you're looking at the wrong symptoms. What you're describing is just being inconsiderate and I'd imagine that you're probably young. Simply paying attention to those bad behaviors is a good start on addressing them. Attempting to be kind, curious, and attentive is a strong strategy. I mean, on some level, that behavior selfish and "narcissistic", but it's not a personality disorder. IME it's not what people are talking about when they are talking about "narcissism". As to NPD... You might look at how well you respond to criticism, and what kinds of criticisms cause you to become upset. The reason that you "couldn't find any book for people who are narcissistic themselves and want to fix that" is that NPD is an issue where people have a fragile sense of who they are so they develop a lot of strategies for not having to encounter personal criticisms; by definition they aren't looking for those kinds of books. Any suggestion that change is necessary is something that feels harmful.
