Myth – Psychotherapists make clients feel immediately better after each session.

This scenario might be convenient for a storyline, but nothing is further from the truth. Clients are not cars, and therapists aren’t mechanics. Clients are active participants while therapists help them face and uncover whatever is bothering them. That process takes time and can be initially difficult and painful. Having feelings stirred up is part of the therapeutic process. When psychotherapists describe the healing trajectory, we often say sometimes things get worse before they get better. But skilled therapists are trained on how to lead clients through the storm into the calm.
