Your Depression Isn't a Brain Problem. It Has an Address.
You've been told your brain is broken. The message arrived with clinical language and a prescription and the implication that something went wrong inside you — a malfunction at the neurological level — that explains why you feel the way you do. You accepted it, probably, because it came from a doctor. Because it came with a framework. Because it was better than nothing.
But it started when everything around you fell apart.
Dr. Joanna Moncrieff at University College London has spent the last decade challenging the dominant model of depression as a chemical imbalance. Her 2022 umbrella review in Molecular Psychiatry, co-authored with a team of researchers, synthesized the available evidence on the serotonin hypothesis and found it does not support the idea that depression is caused by low serotonin levels. Her 2026 follow-up research extends this into a clinical framework: depression caused by real life circumstances — abuse, poverty, unresolved loss, chronic injustice — responds better to changing those circumstances than to medication alone.
This isn't anti-psychiatry. Medication can provide enough stabilization to make change possible. But the change has to happen. And for that, the circumstance has to be named.
The Framing That Hides the Source
For decades, the message has been consistent: depression is a brain disease. Like diabetes, like hypertension — a biological process that can be managed with the right pharmaceutical intervention. This framing is clean. It removes stigma in one direction (it's not your fault, it's your brain). It creates a treatment pathway (here's a prescription). And it keeps the clinical conversation focused on you — your neurochemistry, your brain, your internal architecture.
What it doesn't do is ask what's happening in your life.
If you're depressed because you're in an abusive relationship, that is not primarily a brain problem. If you're depressed because you're working three jobs and still can't pay rent, that is not primarily a brain problem. If you're depressed because you've experienced repeated loss with no adequate support, because you live in a body that society treats with contempt, because you've been told in a hundred different ways that you're not enough and you've started to believe it — these are not brain problems. They are responses. Rational, proportionate responses to genuinely unbearable situations.
The chemical imbalance framing keeps the focus on the person. Not on what's being done to them. That is where the injustice lives.
When Medication Has a Ceiling
This is not an argument against antidepressants. It's an argument for asking the question the medication can't answer.
Even good therapy has a ceiling when nothing changes outside the room. You can develop insight into your patterns every week. You can practice the tools. You can feel the difference during the session. And if you return to the same home, the same relationship, the same work environment, the same financial terror — the nervous system has every reason to stay in alarm. Not because it's broken. Because it's paying attention.
Moncrieff's framework distinguishes between depression that responds primarily to symptom management and depression that is generated by circumstances that require direct address. The second category isn't treated by addressing symptoms. Symptom management without circumstance change is like taking painkillers for a broken leg and calling it healed because you feel less pain.
Your nervous system running on chronic stress is not a malfunction. It is a calibration. And recalibration requires changing what the nervous system is responding to — not just modifying the response.
The Question That Changes Everything
There is a question Moncrieff's research implies, one that is almost never asked in a clinical intake appointment in the standard fifteen minutes:
Was I like this before it happened?
Before the relationship that humiliates you. Before the job that treats you as disposable. Before the loss that didn't get to be grief because there was too much else to manage. Before the thing that happened that you've never told anyone about because you don't think you'd be believed. Before the decade of being told, in ways large and small, that your needs don't matter.
If the answer is no — if you can locate a before — then your depression has a location. It has a circumstance. It has a source that is external to your neurology.
This matters for treatment. It matters for self-understanding. And it matters because the alternative — believing the problem is inside you, inside your broken chemistry — tends to produce a particular kind of helplessness. The broken-brain narrative removes agency at exactly the moment you need it most.
If your depression has an address, you can think about the address. You can make decisions about whether to stay at that address. You can stop optimizing your coping strategies and start asking whether the situation is one a person should be coping with at all.
Sadness in an Unbearable Situation Is Not Pathology
This is the reframe the clinical model doesn't quite get to: some depression is clarity.
Not all of it. There are forms of depression that arise in objectively tolerable circumstances, that are disproportionate to any identifiable external cause, that have genuine neurobiological substrates that respond to medication in ways that aren't mediated by circumstance change. This is real. The heterogeneity of what we call depression matters.
But for a significant portion of the people diagnosed with depression — particularly those who have experienced trauma, chronic stress, relational harm, systemic disadvantage — the experience of being low is not a malfunction. It's an accurate assessment of a situation that is genuinely bad, filtered through a nervous system that has been running on threat-response for a long time.
Calling that clarity doesn't make it feel better. It doesn't lift it. But it does change the question you're answering. Instead of "what's wrong with me?" you get to ask: "what's happening to me, and what would it mean to change it?"
Those are different questions. They lead to different places.
You are not chemically defective. You are someone having a completely reasonable response to something genuinely unbearable. The sadness isn't the problem. The situation is.
