How long does therapy take to work?

A: Honest ranges: many people feel meaningful improvement within 8–20 weekly sessions for focused problems like anxiety or a rough patch; roughly half of clients improve measurably by ~15–20 sessions in outcome research.¹ Deeper pattern work — trauma, long-standing depression, "why do my relationships keep doing this" — is often measured in months to a couple of years, usually with the intensity tapering as you go.

Worked example: 16 sessions at a $100 sliding rate = $1,600 for a solid course of focused therapy — comparable to a root canal and crown, for something you use daily.

Do this: ask your therapist at session one: "How will we know it's working?" And run the fit check at session three — switching early beats quitting late →.
