When the mind treats the worst-case scenario as the most likely one.
Catastrophising is the habit of assuming the worst possible outcome in any uncertain situation and treating it as likely rather than as one possibility among others. It keeps the nervous system constantly on alert.
1 Understand the core chain
- Uncertain future event
- The mind jumps to the worst-case scenario
- The scenario is treated as probable, not just possible
- The body reacts as if it were already happening
- The present moment is lost to dread, exhaustion builds
“Catastrophising spends today’s energy on a tomorrow that, most of the time, never happens that way.”
2 Recognise how it shows up
- Body: Chronic tension, difficulty relaxing, fatigue from constant vigilance.
- Thoughts: “This will end badly”, “Something terrible is going to happen”, “No point hoping for a good outcome.”
- Behaviours: Over-preparing for the worst, avoiding hope “so you won’t be disappointed”, replaying disaster scenarios.
One isolated sign is not enough to define a pattern.
3 The cycle how it keeps going
- Uncertain event
- Worst case imagined and treated as likely
- The body reacts as if it were real
- The present moment is lost to apprehension
- Sensitivity to uncertainty increases
…and back to the start.
4 Explore questions to go further
- Of all possible outcomes, why does my mind land on the worst one?
- Looking back, how often did the catastrophe actually happen?
- What would I feel if I held the outcome as “unknown” rather than “definitely bad”?
5 Go deeper needs and beliefs
Need: Protection from unpredictable pain.
Belief: “If I expect the worst, I’ll be ready and it will hurt less.”
6 Next steps where to go from here
- Write down three possible outcomes, not just the worst one.
- Ask “What is most likely?” instead of “What is the worst?”
- Notice one moment today when the expected catastrophe didn’t happen.
