There are loads and loads of books on psychoanalysis, but you're better off going to a therapist. They will help you know yourself and in knowing yourself you will more easily know others. Doing it on your own will lead to idiosyncracies at best and self-damage at worst because psychoanalysis is one of those disciplines that starts off as a discoursive method but gradually transforms into a skill and perspective on life itself and supposedly in some ways into gnosticism.
