Hello Lonesome

ATM therapy is not an option.
My question really concerns whether/how an individual can begin to explore and unpick one's past traumas or behaviour, perhaps even towards improving oneself, independently of a T?

Are there self help books around this area, for instance, perhaps based upon psychoanalytic theories..?

It just seems there's a particular emphasis placed upon therapy - with understandable reason - which caused me to consider alternatives for those open to change.
