When it comes to mental illness, we know people can get better. According to the American Public Health Association, the success rate for the treatment of depression ranges from 70-80%. In comparison to the rest of medical science, psychology and psychiatry are still in their infancy, so we dont always know why. On the other hand, we do know to paraphrase psychiatrist Irvin Yalom that the most therapeutic thing about therapy is that it gives the patient hope. If you think youre going to get better and your therapist thinks youre going to get better youre more likely to get better. That hope doesnt come by working with a collection of symptoms; instead, it springs from the human being across from you who thinks and feels.
