The worst-case scenario thinking is troublesome because it causes the very problem we're trying to prevent - an unpleasant or difficult situation.

How often does a negative thought turn into catastrophic thinking? A spot on your face becomes a cancerous tumour. Your child not attending a specific school spirals into him not getting a good job. From just entertaining an idea, it quickly turns into a worst-case scenario.

When your thoughts tip from realistic anxieties into unlikely scenarios, take note of it. Also, if your thoughts become catastrophic, notice if you're judging yourself: "I always do this."

We often may not realise when our thoughts become catastrophic. A long-term solution for sharpening self-awareness is mindfulness meditation. It can help you become better attuned to your thoughts.
