From Overwhelm to Exhaustion: Breaking the Stress–Anxiety–Depression Cycle
How Anxiety, Depression and Stress Interact
People often ask me “is this stress? Or anxiety? Or am I depressed?”
The truth is that these experiences are closely connected. They don’t exist in neat little boxes. Understanding how they interact can help you make sense of what’s happening.
Stress: When Life Feels Like Too Much
Stress happens when the demands on you feel bigger than your ability to manage them. For example, deadlines, family responsibilities, financial pressure, big life changes can all drain our mental and emotional batteries.
In small bursts, stress can actually help you perform. But when it becomes constant, your body stays in “on” mode and your nervous system doesn’t get a break. That’s usually where the shift begins and you see signs that let you know that your battery strength is starting to fade. You may feel more irritable, tired, scattered, or overwhelmed than usual.
Anxiety: When Your Mind Won’t Switch Off
Anxiety is the emotional response to anticipating something bad might happen, even if you can’t clearly name the threat or what you fear.
When stress sticks around for too long, your system can become hypersensitive, and you might notice:
Racing thoughts
Trouble sleeping
Tight chest or tense muscles
Constant “what if?” thinking
This is not a sign or weakness. It’s a nervous system that has been under pressure.
Research shows that when people struggle with self-worth, anxiety symptoms can feel more intense, especially if the main coping strategy is avoiding uncomfortable feelings. Avoidance can feel helpful in the moment, but in the long term, it usually keeps anxiety alive and often feeds it.
Depression: When Everything Feels Heavy
If stress and anxiety continue without relief, emotional and physical exhaustion can set in.
Over time, the nervous system can shift from being constantly “on” to feeling completely depleted. That’s often where depression begins to show itself.
Contrary to popular misconceptions, depression isn’t just sadness. Many people describe it more as a heaviness, a slowing down, or a sense of disconnection.
It can look like:
Persistent low mood
Low energy, even after rest
Loss of motivation
Withdrawing from people
Difficulty concentrating
Changes in sleep or appetite
Feeling flat, numb, or emotionally shut down
A harsh inner critic or feelings of worthlessness
For some, depression feels like everything requires double the effort. Simple tasks like replying to a message, getting out of bed, or simply making decisions can feel overwhelming.
For others, depression is less visible. They continue to function, go to work, meet responsibilities, but internally feel empty, disconnected, or exhausted. This is sometimes referred to as “high-functioning” depression.
There is strong evidence linking low self-esteem with depressive symptoms. When someone feels worn down by ongoing stress and anxiety, their sense of confidence and resilience can gradually erode. Over time, they may begin to interpret setbacks more negatively, doubt themselves more frequently, and feel less capable of coping.
Depression also tends to reinforce itself. Low energy reduces activity. Reduced activity lowers positive experiences. Fewer positive experiences deepen low mood. The cycle tightens.
Importantly, depression is not a character flaw. It is not laziness. It is not a lack of gratitude. It is often the result of prolonged emotional strain combined with biological and psychological factors. While it can feel incredibly isolating, it is treatable.
When resilience is strengthened, avoidance is reduced, and self-worth is rebuilt, depressive symptoms can begin to ease.
The Cycle That Forms
When stress and symptoms of anxiety and depression are present, a cycle form. It often looks something like this:
It often unfolds in a pattern like this:
1. Life becomes overwhelming (stress).
Responsibilities build up. Expectations feel constant. There’s little space to rest or reset. Even if nothing dramatic has happened, the ongoing pressure quietly accumulates.
2. Your system stays on high alert (anxiety).
Because the demands don’t ease, your nervous system doesn’t either. You start scanning for problems before they happen. Your thoughts race ahead. Sleep becomes lighter. Your body feels tense. You’re not choosing to be anxious — your system is trying to protect you.
3. You try to push feelings away or power through (avoidance).
You tell yourself to “just get on with it.” You distract yourself. You suppress uncomfortable thoughts. You stay busy so you don’t have to feel what’s underneath.
In the short term, this works. You function. You cope. You survive.
But internally, nothing has actually been processed.
4. Over time, exhaustion and low mood set in (depression).
Constant vigilance is draining. Suppressing emotions takes energy. Eventually, the system runs out of fuel. Motivation drops. Things feel heavier. You may feel flat, disconnected, or hopeless.
And then the cycle reinforces itself.
When avoidance increases, resilience tends to decrease. And when resilience decreases, anxiety and depression often increase.
It becomes a loop.
What Keeps the Loop Going?
Research highlights two important processes at the centre of this cycle:
Experiential avoidance or the habit of trying to suppress, escape, or control uncomfortable thoughts and emotions instead of allowing and processing them.
Psychological resilience or your capacity to adapt, recover, and stay flexible when life is difficult.
When avoidance increases, resilience tends to decrease.
The more you push feelings away, the less opportunity you give yourself to build emotional tolerance. Over time, your system becomes less flexible.
And when resilience decreases:
Stress feels harder to manage.
Anxiety becomes more intense.
Low mood deepens more quickly.
So, the loop tightens:
· Stress fuels anxiety.
· Anxiety fuels avoidance.
· Avoidance reduces resilience.
· Reduced resilience increases both anxiety and depression.
It becomes self-reinforcing, not because you’re doing something wrong, but because your coping system has become overloaded.
But, there’s hope …
If a cycle can be learned, it can also be unlearned.
Therapy works by gently interrupting the loop by reducing avoidance, strengthening resilience, and helping your nervous system feel safe enough to stand down. Change doesn’t happen by “trying harder.” It happens by responding differently.
Here’s how we can do that:
1. Reducing Avoidance (Safely)
Many people cope by pushing feelings down, distracting themselves, or powering through. Therapy creates a structured, contained space where emotions can be approached gradually instead of suppressed.
You learn how to:
Notice uncomfortable thoughts without being consumed by them
Sit with emotions without immediately trying to eliminate them
Respond instead of reacting
When you stop fighting your internal experience, your nervous system doesn’t have to stay on high alert.
Avoidance decreases. Flexibility increases.
2. Regulating the Nervous System
Anxiety isn’t just “in your head.” It’s physiological.
Therapy helps you understand how your body responds to stress and teaches practical regulation skills (e.g., breathing strategies, grounding techniques, cognitive reframing, behavioural pacing).
When the nervous system feels safer, anxiety symptoms reduce.
When anxiety reduces, exhaustion reduces.
3. Rebuilding Psychological Resilience
Resilience isn’t something you either have or don’t have. It’s a capacity that can be strengthened.
In therapy, we:
Identify unhelpful thinking patterns
Strengthen problem-solving skills
Build emotional tolerance
Clarify values and priorities
Reconnect you with sources of meaning
As resilience grows, stress becomes more manageable. Setbacks feel less catastrophic. Recovery becomes faster.
And when resilience increases, symptoms of both anxiety and depression often decrease.
4. Addressing Self-Worth
Low self-esteem often sits quietly underneath both anxiety and depression.
If your internal narrative is harsh, critical, or perfectionistic, stress will feel heavier and anxiety more intense.
Therapy helps you:
Recognise the inner critic
Challenge distorted self-beliefs
Develop a more balanced and compassionate self-view
When self-worth stabilises, the system becomes less reactive.
5. Creating Sustainable Change
The goal isn’t to eliminate stress. Stress is part of being human.
The goal is to help your system respond in a way that doesn’t spiral.
Over time:
Stress becomes information, not threat.
Anxiety becomes manageable, not overwhelming.
Low mood lifts as energy and motivation return.
Small changes compound. The loop loosens. You don’t break the cycle by pushing harder. You break it by responding differently, with support, structure, and strategies that are evidence-informed and tailored to you.
