More information about Self Help:

Self-help or self-improvement is a self-guided improvementóeconomically, intellectually, or emotionallyóoften with a substantial psychological basis.
Many different self-help group programs exist, each with its own focus, techniques, associated beliefs, proponents and in some cases, leaders.
Concepts and terms originating in self-help culture and Twelve-Step culture, such as recovery, dysfunctional families, and codependency have become firmly integrated in mainstream language.

Self-help often utilizes publicly available information or support groups, on the Internet as well as in person, where people in similar situations join together.
From early examples in self-driven legal practice and home-spun advice, the connotations of the word have spread and often apply particularly to education, business,
psychology and psychotherapy, commonly distributed through the popular genre of self-help books.
According to the APA Dictionary of Psychology, potential benefits of self-help groups that professionals may not be able to provide include friendship,
emotional support, experiential knowledge, identity, meaningful roles, and a sense of belonging.
