Psychotherapy differs from coaching in that we do not simply focus on re-framing and finding strategic ways to perform. Rather, we focus on coming into an open and honest relationship with the truth of your experience, no matter what that is. While a coach might help you override your fear, a psychotherapist will bring you in direct relationship to your fear. Where a coach might teach you techniques to push away negative thoughts, a psychotherapist might encourage you to move closer to them, study them, and explore the base root of these thoughts.
The idea in psychotherapy is that the closer we move to that which scares us, the more we liberate from fear. Not from the perspective of moving past it, but instead from developing a working relationship to it.
