What If It Goes Wrong? A CBT Approach to Overthinking and Worst-Case Thinking
Struggling with overthinking or worst-case scenarios? Learn how CBT helps break the cycle of worry and regain control.
“What If It Goes Wrong?”
Many people experience thoughts like:
“What if I fail?”
“What if something bad happens?”
“What if I can’t cope?”
These thoughts can feel urgent, important, and difficult to switch off.
You might find yourself:
Replaying situations in your mind
Trying to predict every possible outcome
Mentally preparing for the worst
Feeling stuck in loops of overthinking
If this sounds familiar, you’re not alone.
This pattern is often referred to as worst-case thinking, and it’s a common feature of anxiety.
What Is Overthinking?
Overthinking is when your mind tries to solve uncertainty by thinking more and more.
It often feels like:
You’re being responsible
You’re preparing yourself
You’re trying to stay in control
But in reality, it can lead to:
Mental exhaustion
Increased anxiety
Difficulty making decisions
Feeling stuck or overwhelmed
Why Do We Jump to the Worst-Case Scenario?
From a CBT perspective, the brain is wired to:
Spot potential threats
Anticipate problems
Keep you safe
Worst-case thinking is your mind’s way of asking: “What’s the most dangerous outcome, and how do I prepare for it?”
The problem is:
These thoughts often overestimate risk
And underestimate your ability to cope
The Cycle of Overthinking
Overthinking tends to follow a pattern:
A trigger (e.g. uncertainty, decision, situation)
“What if” thoughts
More thinking to try to find certainty
Temporary relief (briefly)
Anxiety returns (often stronger)
This creates a loop where thinking feels necessary, but actually keeps anxiety going.
Why Thinking More Doesn’t Help
It’s natural to believe “If I just think about this enough, I’ll feel better.”
But with uncertainty, there is often:
No clear answer
No guaranteed outcome
So the mind keeps searching without resolution.
This is why overthinking often feels:
Endless
Draining
Unproductive
A CBT Approach to Breaking the Cycle
Here are some practical, evidence-based strategies:
Notice the Pattern
The first step is recognising when you’re overthinking.
Ask yourself: “Am I solving a problem, or going in circles?”
If there’s no clear outcome or action, it’s likely overthinking.
Shift From Prediction to Coping
Instead of asking: “What if it goes wrong?”
Try: “If it did go wrong, how would I handle it?”
This helps you:
Feel more capable
Reduce fear
Focus on resilience, not risk
Challenge the Bias Toward the Worst Case
The mind naturally focuses on the most negative outcome.
Gently ask:
What’s the most likely outcome?
What are other possible outcomes?
Have I coped with difficult situations before?
This creates a more balanced perspective.
Set Boundaries Around Thinking
Trying to stop thoughts completely can make them louder.
Instead:
Allow a limited time to think things through
Then gently redirect your attention
This helps reduce the feeling of being “stuck” in your head.
Take Small, Real-World Action
Overthinking often replaces action.
Ask “What’s one small step I can take right now?”
Even small actions can:
Reduce uncertainty
Build confidence
Interrupt the thinking cycle
Build Tolerance for Uncertainty
A key part of CBT is learning that you don’t need certainty to cope.
This might involve:
Making decisions without having all the answers
Letting some questions remain open
Resisting the urge to “figure everything out”
Over time, this reduces anxiety significantly.
When Overthinking Becomes a Problem
It may be helpful to seek support if:
You feel stuck in constant “what if” thinking
It’s affecting sleep, work, or relationships
You struggle to switch off
Anxiety feels persistent or overwhelming
How Therapy Can Help
At Shire Therapies, we use Cognitive Behavioural Therapy (CBT) to help you:
Understand your thinking patterns
Break cycles of worry and rumination
Develop more balanced, helpful thinking
Build confidence in handling uncertainty
Therapy isn’t about “stopping thoughts”, it’s about changing your relationship with them.
Final Thought
Overthinking often comes from a place of trying to protect yourself.
But you don’t need to predict every outcome to be okay.
Learning to step out of the cycle even slightly can make a meaningful difference.
