It tends to happen without a clear moment. The mornings are darker, the evenings close in, and at some point in October you notice that everything has become slightly more effort than it was in September. The walk after work, the call you meant to make, the plans you would normally have said yes to.

Then comes the part that does the most damage: the explanation. Most people reach for a personal one. I have got lazy. I have lost my drive. Something is wrong with me. Rarely does anyone say, “the season changed and so did my week.”

This post is about the second explanation. It covers what shifts in autumn, why it is easy to mistake for a personal failing, how to tell resting from retreating, and where to start when you do not feel like starting anything. Being harsh with yourself about it is one of the things that tends to make it heavier, so that comes into it too.

Three Things That Change in Autumn

None of these are about willpower, and all of them are reasonably predictable.

• The light goes, and a good deal of your drive goes with it. Shorter days mean less daylight, and for many people it is dark on the way to work and dark again on the way home. Outdoor light is far brighter than indoor light even when the sky looks dull, so a day spent mostly inside in autumn can contain very little of it. Less light tends to mean less energy and less appetite for starting anything.
• The year’s plans run out of road before the year does. Summer is full of things with dates attached: holidays, weddings, long evenings that were still usable. By October most of that has happened, and the next landmark is not until January. With nothing ahead to aim at, days stop being something you are heading through and become something you are getting through.
• Rest gets confused with withdrawal. When the evenings are dark, staying in feels sensible, and often it is. The trouble is that the two look identical from the outside and feel very similar at the time. One restores you. The other quietly shrinks your week. More on telling them apart below.

Taken together, these squeeze out the easy, mood-lifting parts of an ordinary day: being outside, seeing people in passing, having a reason to leave the house. That is the real mechanism, and it matters because it points to something you can change, which a vague sense of being “not yourself” does not. If everything has also started to feel like too much, why you feel emotionally overwhelmed explains what is going on underneath.

Autumn Did Not Make You Lazy. It Took Away the Scaffolding.

Think about everything that holds an ordinary summer week up. The light that gets you out of bed, the evening that is still usable after work, the plans in the diary, the friend you bump into on the way past. Most of it works invisibly. You do not experience it as structure. You experience it as simply being someone who does things.

Then it goes, and the week does not collapse so much as sag. Because the supports were never visible, their absence does not register as a change in circumstances. It registers as a change in you. That is why it feels like a personal failing rather than a seasonal one.

This is the part worth holding onto. The same person in a different season needs a different structure. Not more willpower: structure. And structure is something you can build deliberately, which is good news on the days when motivation is the thing in shortest supply.

Is Feeling Low Every Autumn Normal, or Something More?

The myth: “Something is wrong with me.”

For most people, a dip in autumn is a response to a real change in light, routine and opportunity, and it responds to practical changes. It is not evidence of weakness, and it does not mean your mood is permanently lower than other people’s.

When it is more than the autumn blues

For some people the pattern is stronger and more regular. Low mood that comes back each autumn and winter, and lifts in spring, is recognised clinically as a seasonal pattern of depression, often called seasonal affective disorder. It tends to involve more than a dip in energy: changes in sleep and appetite, difficulty concentrating, losing interest in things, and feeling low most of the day.

If low mood is part of a longer-running pattern of ongoing stress, exhaustion, or anxiety that has stopped easing, autumn can simply be the season in which it becomes impossible to ignore. That is still worth taking to someone, and it is not a reason to wait until spring.

Resting or Retreating? How to Tell the Difference

This is the question that does most of the damage in autumn, because both feel like looking after yourself. Rest restores you and you come back. Withdrawal feels like rest at the time and leaves you with less than you started with.

A few questions help sort them:

• Are you moving towards something or away from something? An evening in because you want a quiet night is rest. An evening in because the alternative felt like too much, again, is closer to avoidance.
• How do you feel afterwards? Rest usually leaves you a little more able. Withdrawal tends to leave you flatter, a little more behind, and with a slightly harder time doing the same thing tomorrow.
• Is the list of things you do getting shorter? One quiet evening is nothing. Three weeks of cancelled plans, unanswered messages and dropped routines is a pattern, and it is the pattern that keeps low mood going. This is the same avoidance that sits behind putting things off: relief now, at a cost later.

None of this is a reason to push yourself into a full social calendar. It is a reason to notice the direction of travel, and to keep one or two small threads in place even when you would rather let them all go. And if the long evenings tend to fill up with a busy, circling mind, these tips for calming overthinking are a good companion to the steps below.

What Helps: Act First, Feel Second

The approach with the strongest evidence for low mood runs against instinct. Behavioural activation starts from the idea that most of us operate on an inside-out rule: when I feel better, I will do things. Low mood breaks that rule, because the feeling does not arrive first. So you reverse it. You choose a small action, do it whether or not you feel like it, and then notice what it does to your mood. Motivation is more often the result of action than the condition for it.

It is not forced cheerfulness, and nobody is asking you to enjoy anything. It is a small, structured test of what changes how your days feel. It sits within the CBT tradition, and NICE guidance for depression in adults includes it among the recommended psychological therapies. A large UK trial (Richards et al., 2016, in The Lancet) found it worked about as well as CBT while needing less training to deliver, which is part of why it works well as a self-help starting point.

In practice it comes down to three moves: look at what your week contains, choose small actions linked to what matters to you, then schedule and do them and check what happened. For autumn specifically, these are the ones I would start with.

It is also worth being gentle about how you go about it. If your reaction to a slow start is to criticise yourself for it, that adds a second problem to the first. The aim is to find out what helps, not to prove you can manage.

Low Mood and Dark Evenings in York

The clocks go back on Sunday 25 October, and the first week after that is when many people notice the shift most sharply: leaving work in the dark, and the afternoon ending before you have quite got going. It is worth planning for rather than waiting for it to land. Decide in advance what the first dark evening will contain, and put your daylight walk somewhere in the day when you can reach it, even if that means lunchtime.

If low mood has been more than a seasonal dip and you are in York or the surrounding area, your GP is a reasonable first conversation. You can also refer yourself to NHS Talking Therapies without going through them, and the Access to Mental Wellbeing Team is the local route into wider mental health support. Privately, my guide to finding a therapist or psychologist in York covers the options, and it helps to know what the different practitioner titles mean before you choose. The psychological therapy page sets out how I work, drawing on a range of evidence-based models rather than a single one.

If anxiety tends to come along with the low mood, it is worth reading about when anxiety is a sign it is time for therapy, and about the simple self-care practices that tend to hold up on low-energy days.

As for my own position: Sennah Psychology therapy is currently paused while I am on maternity leave, so I am not taking new clients at present. The waiting list is open and I will be in touch as soon as I return. Clinical supervision enquiries are open as usual.
