High functioning depression is what people call depression that leaves your work and your obligations intact. You want somebody to see how flat it has become, and you make certain there is nothing to see. This article explains what your functioning is holding up, what it costs you, and where the work begins.
Clinical insights from 22 years in psychotherapy
I’m Mark Colclough, MA, psychotherapist in Copenhagen. Qualified at the Psychosynthesis Education Trust and the University of East London. 22 years of full-time, face-to-face clinical practice.
- No real reason. My clients spend the first minutes of a first session explaining why their difficulty does not really warrant one.
- What finally brings them. What brings somebody to me is rarely the low mood itself, it is what the low mood has started to cost the people at home.
- The standard. The hardest part of this work is showing a client that the standard they hold themselves to is not the ordinary human one.
Clinical notes: My observations are anonymised and compounded from my session notes since 2004.
Is high functioning depression a real diagnosis?
It is a real experience with no formal diagnosis behind it. No diagnostic manual lists the phrase. The terms clinicians use are major depressive disorder, for depression that arrives in episodes, and persistent depressive disorder, previously called dysthymia, where low mood runs for at least 2 years1. Neither of those has anything to say about how much you are still getting done, which is why the informal phrase caught hold: it names the part the clinical language leaves out.
I would not spend long working out which of those terms fits you, and I would not want you reading criteria at midnight and scoring yourself against them. That tells you about the midnight. What is worth your attention is the distance between how your life looks and how it feels, and how long that distance has been there. Duration does damage of its own: people whose depression has run on rather than passed through in episodes report more than twice as many days when their mental health limits what they can do1. A year of this is not a worse week.
What does it actually feel like from the inside?
Flat is the word my clients reach for, and flat is not sad. Sadness has an object and some movement in it. This has neither. You are not weeping at your desk, you are getting through a Tuesday with the sound turned down, and what has gone is the pull towards things that used to pull. The clinical word for that is anhedonia, the loss of pleasure and of anticipation, and it is the part of this that passes most easily for a settled, serious adulthood.
It shows in the body before it reaches your thinking. Waking at four with your heart going faster than the morning deserves. A weight through the shoulders and the jaw that sleep does not touch. Eating because it is one o’clock rather than because you want anything. Sex becoming one more thing that would require getting started.
The explanations arrive last, and they arrive sounding reasonable. You are tired because the quarter was hard. You are quiet because you are busy. You will feel better when the project ships. Then the project ships, and the Monday after it is identical to the Monday before, and that identical Monday deserves more of your attention than the flatness does.
Why does nobody notice?
People look for a drop in output, and output is the last thing to go. Depression gets recognised by its visible consequences: the missed work, the cancelled plans, the life that stops. Yours has not stopped.
- Colleagues. They see the work, and the work is the part you have protected longest.
- Friends. They see you turn up, and you do turn up.
- A partner. They get the hours left after work has taken the good ones, and what reaches them looks like being loved less.
- You. You know what it costs, and you have had years of practice at calling that cost normal.
- Abroad. Move country and nobody around you holds a picture of how you used to be, so there is no earlier version of you for anyone to miss.
Going unnoticed is ordinary rather than a failure of expression on your part. Even where services are easiest to reach, only about a third of people with depression in high income countries receive treatment for it2. Read more about struggling in silence.

What is the functioning protecting?
The functioning is doing a job, and it is worth knowing the job before you try to put it down. What follows is my clinical judgement rather than a research finding.
- An identity. If you have been the reliable one since childhood, a missed deadline threatens a great deal more than the deadline.
- Other people. Somebody has to keep the household running, and you settled long ago on it being you.
- Not finding out. While the output holds, the question of how bad this has become stays unanswered, and part of you prefers it unanswered.
- The good hours. Work gets them, because work has witnesses. Whoever is waiting at home gets what is left.
- Being seen. You want one person to notice without being told, and you are careful to give them nothing to notice.
That last one costs the most at home. What I see is a partner who asks twice what is wrong, hears that nothing is, and stops asking, and then the quiet that follows gets taken as evidence that nobody was interested. Neither of you is lying, and neither of you is being told the truth. Read more about feeling disconnected from your partner.
How is this different from a low patch or ordinary tiredness?
A low patch lifts when circumstances change, and this barely moves. A bad fortnight after a bad event is ordinary life. What is worth noticing is not how low the mood goes but how little it answers to anything: a free weekend arrives, nothing is required of you, and the flatness is exactly where you left it.
Tiredness takes away what you are able to do. This takes away what you want, which is harder to see, because wanting nothing in particular feels like calm rather than loss. In the people I work with the narrowing comes in an order. The optional things go first, then the social ones, then anything not strictly required, until what is left is work and sleep. From the outside that reads as a serious person with a demanding job, and from the inside it goes years without a name.
How do you begin to change it?
You stop using your output as the measure, and you start on what the functioning is for.
- One line an evening. For a week, write one line: what did I want to do today, rather than have to do? This is a suggestion for noticing, not a measure of anything.
- Read the blanks. 7 evenings of blank lines is the most useful thing the exercise will give you.
- Count the cost. Ask what share of what you have goes into holding the surface steady, and what is left for anything you would choose.
- Say one true sentence to one person. The first honest sentence is short, and it is the hardest.
- Let the body go first. Walking, eating at hours that make sense, going to bed with something still left in you. None of that lifts a depression, and it changes what you have to think with.
- Expect sustained work rather than a short course. Psychotherapy for depression that has become chronic shows a small but real effect against no treatment, and the effect grows with the number of sessions3.
- Start before you are forced to. Coping is not a qualification you have to lose first.
In the room I work on what the functioning protects, what you believe would happen if it stopped, and what it would take to want something again. That is slower than relief and it holds longer.
These steps are not enough when the flatness is itself what judges whether any of this is bad enough to count, when the narrowing has run for years rather than months, or when the one honest sentence has nowhere to land because there is no longer anybody to say it to. That is where an article reaches the end of what it can do, and individual work with a therapist is the next step.
Questions people ask
Will a therapist take me seriously if I am still coping?
Yes, and the coping is the first thing I want to understand rather than a reason to turn you away. Nothing has to have collapsed before this work is worth starting.
What happens in a first session for something like this?
You describe how things are, and I ask what the functioning costs you and what it protects. By the end we agree whether to continue and how often.
How long does therapy for long-standing flatness take?
Depression that has run for years asks for sustained work rather than a short course. I would rather agree a first block of sessions and review it with you than name a finishing date.
Would individual therapy or couples therapy suit this better?
Individual therapy fits when the flatness is yours to understand, and couples work fits when most of the damage is now happening between you and your partner. A first session settles that better than deciding in advance.
Can I start with something smaller than a full session?
Yes, there is a free 30 minute call, and it is enough to tell whether talking to me is any use to you. It commits you to nothing.
If you keep going while feeling flat inside, I offer therapy for high-functioning depression as a place to stop performing for a while.
