Existential therapy is grounded in the understanding that human beings are not defined by a fixed nature, but are continually shaping themselves through the choices they make. Drawing on the work of thinkers such as Jean-Paul Sartre, Viktor Frankl, and Irvin D. Yalom, it recognises that with freedom comes responsibility, and that this can give rise to anxiety, uncertainty, and questions about meaning. Rather than viewing these experiences as problems to be eliminated, existential therapy sees them as a natural and important part of being human. It explores themes such as identity, purpose, isolation, and mortality, helping individuals to reflect more deeply on how they are living and what matters most to them. At its heart, this approach values authenticity, encouraging people to live in a way that is true to their values, while placing strong emphasis on the therapeutic relationship as a genuine, open, and collaborative encounter.
