Existential psychotherapy is based on the philosophical belief that human beings are alone in the world, and that this aloneness can only be overcome by creating one's own meaning, and exercising one's freedom to choose.
The existential therapist encourages clients to face life's anxieties head on and to start making their own decisions. The therapist will emphasize that, along with having the freedom to carve out meaning, comes the need to take full responsibility for the consequences of one's decisions. Therapy sessions focus on the client's present and future rather than their past.
