When someone says 'I tried therapy and it didn't work', they usually mean: 'I had six sessions of generic talk therapy with the first therapist available, and it didn't transform my life.' The actual fix is often a different modality, different therapist, or different number of sessions — not abandoning therapy altogether.
Wrong modality is the most common reason
Different problems respond to different therapies. CBT works for anxiety, OCD, and acute depression. EMDR works for single-incident PTSD. DBT works for emotion regulation and borderline patterns. ACT works for chronic conditions and values-based change. Psychodynamic works for relationship patterns rooted in early experience.
Going to a generic talk therapist with OCD and getting open-ended 'how does that make you feel' sessions for a year will not help. ERP (exposure and response prevention) within CBT will.
Wrong therapist is the second-most-common reason
Even within the right modality, fit matters. Outcomes correlate more with therapeutic alliance (the working relationship) than with technique. If after 3-4 sessions you don't feel understood, the therapist isn't right for you — even if they're objectively good.
Switching therapists isn't failure. NHS Talking Therapies lets you request a change. Private therapy: BACP and BABCP directories list registered therapists with searchable specialisations.
Wrong dose is the third
Six sessions is enough to start; not enough for most lasting change. Most evidence-based therapies show benefit at 12-20 sessions for moderate problems, longer for complex trauma or chronic patterns. Stopping at session 6 because 'it's not working yet' is common and premature.
What to try if previous therapy hasn't helped
Identify what your specific problem is (not 'I'm anxious' but 'I have panic attacks when I have to give presentations'). Find the modality with strongest evidence for that problem. Look for therapists who name that specialisation. Commit to 12 sessions minimum before evaluating. Track changes in symptoms numerically (PHQ-9 for depression, GAD-7 for anxiety — both free online).
Therapy that doesn't work usually wasn't the right therapy. The right modality plus the right therapist plus the right number of sessions has strong evidence — give it a fair chance before concluding talk therapy isn't for you.
