Catastrophising: When You Feel Certain the Worst Will Happen

When your thoughts say, “The worst is going to happen — it’s bound to,” the future can feel decided before anything has happened. You do not have to force yourself to think positively or make the thought disappear. We can start by separating what feels certain from what you actually know.

1. A frightening prediction is not a settled fact

Perhaps someone asks to speak with you tomorrow, and your mind jumps straight to losing your job. Or a difficult week becomes proof that everything is about to fall apart. This jump towards the worst outcome is often called catastrophising. Sometimes it also includes a second prediction: “And if that happens, I won’t cope.” Both parts deserve a gentle look, rather than an argument with yourself.

The NHS describes anxiety as something that can affect thoughts, feelings, physical sensations and behaviour. Feeling frightened can make a prediction seem convincing, but the feeling does not establish what will happen. Try changing “This is bound to happen” to “I’m having the thought that this is bound to happen.” That wording does not deny a real concern. It simply leaves room to examine it.

2. Separate possible, likely and known

Something can be possible without being likely, and likely without being certain. When you are caught in a frightening prediction, those distinctions are easy to lose. NHS guidance on anxiety recommends noticing anxious thoughts and looking at the evidence for them. This is not about proving that nothing bad ever happens. It is about checking whether the conclusion goes further than the information you have.

Take the message, “Can we talk tomorrow?” What you know is that someone wants a conversation. What you do not know is why. Losing your job might be one imagined explanation, but a routine update or a question might fit the same message. You do not need to calculate exact odds. A more accurate sentence could be: “I don’t know what this conversation is about yet. I can prepare a little without treating disaster as confirmed.”

  • Known: What could a camera, message or document confirm?
  • Predicted: What am I adding about the future?
  • Alternative: What is one other explanation that fits the facts?

3. Let the present have a turn

You may find it difficult to examine a thought while you are pacing, gripping your phone or bracing for news. You can pause the reasoning task for a moment. NHS anxiety guidance includes relaxation and calming breathing among approaches that can help some people. You do not have to feel completely calm before continuing, and becoming calm is not a test you need to pass.

Try a simple orientation pause: notice the chair beneath you, look at an ordinary object and name where you are. If it feels comfortable, let your breathing stay gentle and unforced. If focusing on breathing feels uncomfortable, leave it alone and describe the object instead — its colour, shape and position. The purpose is not to make the future safe by doing an exercise. It is to give some attention back to the place you are actually in.

4. What helps: make a balanced thought and a small plan

A balanced thought is believable, not relentlessly cheerful. “Everything will be wonderful” may be too far from how you feel. Try: “This could be difficult, but I don’t know the outcome yet,” or “If there is a problem, I can find out what support is available.” NHS information describes cognitive behavioural therapy, or CBT, as a treatment that works with patterns in thinking and behaviour. These small questions draw on that approach, but they are not a substitute for individual care.

Next, ask whether there is a useful action available today. Before a meeting, you might write down two questions. Before a deadline, you might identify the first unfinished task. If there is nothing useful to do now, choose an ordinary activity for the next few minutes: make lunch, sit beside someone or put away a few things. You are not declaring the worry unimportant. You are deciding that it does not need to occupy every available moment.

  • Name the prediction in one sentence.
  • Write one fact that supports it and one fact that limits it.
  • Choose a more balanced sentence you can genuinely believe.
  • Take one proportionate action, then pause the planning.

5. When the thought comes back, you have not failed

A frightening thought may return after you have already considered it carefully. That does not mean your earlier answer was useless, or that the thought has become more accurate. Mind describes worries about the future and difficulty controlling worry as experiences that can accompany anxiety. You do not need to treat each return as a fresh instruction to investigate everything again.

You might say, “There’s that prediction again. Has any new information arrived?” If there is genuinely new information, respond to it. If there is not, you can use your earlier balanced sentence and return to the next small activity. Avoid turning this into another rule you must follow perfectly. Some days you will get pulled back into the thought several times. Each return to the present can be small and unfinished.

6. What if something really could go wrong?

Some worries begin with real uncertainty: a job under threat, an unpaid bill or a strained relationship. You do not have to call a genuine difficulty “just anxiety”. The useful distinction is between responding to what is happening and mentally living through the most frightening version of what might happen. A realistic plan can acknowledge risk without assuming that the worst outcome has already been decided.

Keep the plan modest: “If this happens, my first step would be this, and I could contact this person or service.” You do not need a response to every possible branch of the future. Nor do you have to promise yourself that you could manage everything alone. If there is a current safety issue, prioritise practical protection and appropriate help rather than a thought exercise.

  • What needs attention today, rather than in an imagined future?
  • What would my first step be if the feared event happened?
  • Who could help with the practical or emotional part?

7. How Behind 6 can sit alongside you

You can use Behind 6 as a companion for this moment, rather than another task to complete. Choose Stay With Me if you would like company while you pause. In the journal, try just two lines: “My mind predicts…” and “What I know today is…” If planning feels useful, use My Day for one manageable next step — not a whole-day rescue plan.

My Safe Place can be somewhere to return your attention when future-focused thinking takes over. If faith is welcome today, you might choose the Bible space or the optional prayer below; you do not need to turn either into a lesson or find an immediate answer. These options are invitations, not a checklist. Behind 6 is a companion, not an emergency service or a replacement for professional support.

8. When to get more help

Consider speaking with a GP or mental health professional if worry is hard to control, keeps disturbing sleep, leads you to avoid everyday activities or is affecting work and relationships. You do not need to wait until you can no longer manage. NHS guidance describes talking therapies, including CBT, and other treatment options for persistent anxiety. A professional can help you explore what is happening and what support fits your circumstances.

You could begin with: “I keep feeling certain that something terrible will happen, and it’s affecting my day.” You do not need a diagnosis or a polished explanation to ask for support. If you feel unable to keep yourself safe, or there is immediate danger, contact local emergency services or a crisis line. For this moment, the aim is smaller than solving the whole future: notice what is known, find the next appropriate step and let support be part of it.
