If you’ve tried more than one antidepressant, sat through months of therapy, and are still waking up under the same weight, there’s a name for what you’re experiencing — and it isn’t a character failing.
What treatment-resistant depression actually means
Clinically, treatment-resistant depression (TRD) describes depression that hasn’t responded sufficiently to at least two adequate courses of antidepressant treatment. It affects roughly a third of people diagnosed with depression, and it is a specific, recognised pattern — not a sign that someone hasn’t tried hard enough.
You are not failing treatment. Treatment hasn’t yet reached the part of the illness it needs to.
This distinction matters. People with TRD often internalise their lack of response as personal failure, when the more accurate explanation is that conventional treatments are targeting a pathway that, for them, isn’t where the underlying problem lies.
The signs to look out for
TRD is usually identified through a pattern that includes:
Why serotonin-based treatments can fall short
Most antidepressants work primarily on the brain’s serotonin system. For many people this is highly effective. But for others, serotonin simply isn’t where the underlying problem lies — which is part of why an entirely different approach, such as ketamine-assisted psychotherapy, can reach places conventional treatment cannot.
What comes next
If this pattern sounds familiar, the most useful next step isn’t to try yet another medication in isolation — it’s a proper assessment with someone who can look at your history as a whole and tell you honestly what might help.
