If you’ve been depressed before and come out the other side, the thought of ever going back to how you felt can be terrifying.

That’s especially true since depression doesn’t necessarily overwhelm you all at once. Often, it creeps up on you little by little, and you only realise it when it’s fully holding your head beneath the water. Here are some subtler signs that your mental health might be starting to suffer that are worth paying attention to. If you notice them, it’s a good time to talk to someone you trust, whether that’s a friend, family member, or therapist. You can even call Samaritans 24/7 at 116 123. The bottom line is, you don’t have to suffer alone.
1. You’re slowly but surely losing interest in things you usually enjoy.

If you start finding hobbies, social plans, or even your favourite shows less appealing, it might be a sign. It can feel like nothing really grabs your interest the way it used to. Even simple pleasures can start to feel like too much effort. This disinterest can sneak up, making life feel a little duller over time. It’s a subtle shift that’s easy to overlook.
2. Feeling more tired than usual.

When getting out of bed feels harder, even with enough sleep, it could be more than just fatigue. Exhaustion with no clear cause can be a red flag, making everyday tasks seem more difficult. It’s not just physical tiredness; it’s a deeper, draining feeling. Little by little, energy seems harder to find. This kind of fatigue can make life feel like a heavier lift.
3. Noticing changes in your appetite.

Whether you’re eating more or less than usual, shifts in appetite can sometimes mean that depression is creeping in. Food might not taste as satisfying, or cravings may become a way to cope. You might find yourself snacking aimlessly or losing interest in meals altogether. These changes can feel small but add up over time. Appetite shifts often reflect deeper emotional changes happening beneath the surface.
4. Finding it hard to focus.

Concentration might start slipping, making it harder to stay engaged with work or simple tasks. You may notice your mind wandering or feeling “foggy” without a clear reason. Even things you usually handle easily might start feeling confusing or overwhelming. Losing focus can make everyday life feel like a series of obstacles. It’s frustrating, and often one of the first signs something’s off.
5. Sleeping too much or struggling with insomnia.

Changes in sleep patterns are often linked to mental health shifts. Sleeping more than usual might be an escape, while insomnia can leave you feeling restless. If your usual sleep habits are disrupted, it can leave you feeling off-balance and disconnected. Sleep changes might seem like a random phase but can sometimes be a sign of depression creeping back. Rest becomes harder to find, even when you’re tired.
6. Feeling more irritable or short-tempered.

Sometimes, depression shows up as irritability, making you feel more easily annoyed or frustrated. Small things that didn’t bother you before might suddenly feel overwhelming. This shift can strain relationships and make socialising feel like a chore. It’s not always obvious, but a rising sense of irritability can point to something deeper. Emotional “flare-ups” can be a way depression quietly manifests.
7. Avoiding social interactions.

If you start turning down invites or dodging calls, it might be more than just needing some downtime. Socialising can feel exhausting, and the idea of connecting with other people might start to feel draining. Slowly, isolation becomes more appealing, even if it’s not what you truly want. Avoiding people can feel like a way to cope, but it can deepen feelings of loneliness. A pull toward solitude can signal a deeper struggle.
8. Feeling numb or detached.

Sometimes, depression doesn’t feel like sadness; it can feel like nothing at all. Emotions seem muted, like you’re going through the motions without feeling truly present. The numbness can make it hard to enjoy moments or connect with people. It’s like a filter over everything, keeping you from fully engaging with life. Feeling detached can be one of the more subtle signs of depression.
9. Having less patience with yourself.

Self-criticism might become more common, with little things feeling like bigger personal failures. You might catch yourself being unusually hard on yourself for small mistakes or setbacks. So much self-judgment can make simple challenges feel daunting and lower your confidence. Over time, it starts to feel like you’re constantly falling short. The way you talk to yourself can often reveal shifts in your mental state.
10. Becoming disorganised or neglecting responsibilities.

If staying on top of things like bills, chores, or work tasks starts to feel overwhelming, it might be a sign. Procrastination can sneak in, making even simple tasks feel like mountains to climb. Disorganisation isn’t always just a messy habit—it can reflect feeling overwhelmed and disconnected. Slowly, life starts feeling more chaotic, which only adds to the stress. Falling behind on things can often mean that you’re struggling internally.
11. Feeling physically tense or achy.

Depression doesn’t just affect your mind; it can show up in your body as tension or unexplained aches. You might feel stiff or sore, even without any physical strain. The discomfort can make it hard to relax, adding to a general sense of unease. It’s easy to ignore, but these physical signs often go hand-in-hand with emotional struggles. Aches and tension can reflect the weight of mental stress.
12. Turning to comfort behaviours more often.

If you’re reaching for comfort foods, binge-watching, or other habits to escape more often, it might point to something deeper. These coping mechanisms provide quick relief but can sometimes be a way of avoiding how you’re really feeling. It’s not about the behaviour itself, but how often you rely on it to fill an emotional gap. Over time, these habits can start to add up. Increased reliance on “comfort” can be a sign depression is creeping back in.
