Living with a long-term or life-limiting health condition can bring a particular kind of anxiety. It is often not simply anxiety about what is happening now. It is anxiety about what might happen next. You may find your mind regularly moving into the future:
- “What if my symptoms get worse?”
- “What if the treatment stops working?”
- “How will I cope if I become less independent?”
- “What does this mean for my future?”
- “What if I can’t manage?”
For many people, these questions can feel impossible to switch off. Even during moments of relative calm, the mind may continue scanning ahead, searching for potential problems and trying to anticipate every possible outcome. This can be exhausting. Yet it is also deeply understandable. When living with uncertainty, the mind naturally wants answers. The difficulty is that health-related uncertainty often provides very few.
Why uncertainty feels so difficult
Human beings generally prefer certainty. We like knowing what to expect. We make plans, set goals, create routines, and imagine futures that feel relatively predictable. Long-term health conditions can disrupt this sense of predictability. Symptoms may fluctuate unexpectedly. Appointments may bring new information. Treatment outcomes may be unclear. Even when things are relatively stable, there can be an awareness that circumstances could change. This uncertainty can feel deeply unsettling because it challenges one of our most basic psychological needs: the desire to feel safe and in control. From an evolutionary perspective, our minds are designed to anticipate threats. The brain is constantly asking questions such as “What could go wrong?”, “How can I prepare?”, “What should I watch out for?” In many situations, this ability to anticipate future difficulties is useful. It helps us plan, solve problems, and respond to challenges. However, when facing circumstances that cannot be fully predicted or controlled, this same system can become overactive. Instead of helping us prepare, it can leave us trapped in cycles of worry.
When planning becomes worrying
One of the ideas often explored in Cognitive Behavioural Therapy (CBT) is the difference between productive planning and unproductive worry. At first glance, the two can feel very similar. Both involve thinking about the future. Both can feel important. Both can create a sense of urgency. The difference lies in whether the thinking leads to meaningful action. Planning might sound like:
- “I’ll speak to my consultant about treatment options”,
- “I’ll make sure I understand the support available if my needs change”,
- “I’ll discuss practical arrangements with my family”.
These thoughts tend to be specific, focused, and action-oriented. They move us towards something constructive. Worry, on the other hand, often sounds different:
- “What if everything gets worse?”,
- “What if I can’t cope?”,
- “What if something terrible happens?”,
- “What if my future is nothing like I hoped?”
These thoughts are usually broader, more hypothetical, and often impossible to answer with certainty. The mind keeps searching for reassurance but rarely finds it. Instead, one question leads to another, and then another. The result can feel like being stuck on a mental treadmill - expending energy without actually moving forward.
The false promise of certainty
One reason worry can become so persistent is that it often presents itself as a solution. The mind may convince us that if we think about a problem long enough, we will eventually find certainty. However, uncertainty is not always a problem that can be solved. Sometimes it is a reality that must be lived with. This can be particularly true for people living with long-term or life-limiting conditions. No amount of thinking can fully guarantee what will happen in the future. No amount of worry can completely eliminate risk. Yet many people find themselves repeatedly returning to the same thoughts because the mind continues searching for an answer that does not exist. From an ACT perspective, this can be understood as a struggle against uncertainty itself. We become caught in an ongoing effort to feel completely certain before we allow ourselves to relax, engage with life, or feel safe. The difficulty is that complete certainty is rarely available. Waiting for it can mean postponing life indefinitely.
Living alongside uncertainty
Acceptance and Commitment Therapy (ACT) offers a different approach. Rather than asking how we can eliminate uncertainty, ACT encourages us to consider how we might live alongside it. This is not about liking uncertainty. Nor is it about pretending difficult realities do not exist. It is about recognising that uncertainty is already present and considering how we want to respond to it. For example, you may not know how your condition will progress over the coming years. You may not know what future treatments will be available. You may not know exactly how your circumstances will change. These unknowns can be frightening. At the same time, there may be things you do know. You know where you are today. You know what matters to you. You know the people who support you. You know the choices available in this moment. ACT encourages us to bring attention back to these aspects of experience rather than becoming entirely consumed by unanswered questions about the future.
When the mind travels forward
Many people notice that anxiety increases when their attention becomes almost exclusively focused on future possibilities. This is understandable. The future exists largely in the imagination, and when the mind is anxious, it often fills those imagined futures with worst-case scenarios. The problem is not that difficult outcomes are imagined. The problem is that the mind can begin treating those possibilities as though they are happening right now. You may notice your body responding with tension, fear, sadness, or overwhelm, even though the feared event has not occurred. One helpful question can be: “What is actually happening in this moment?” Not because future concerns are irrelevant, but because our minds sometimes lose contact with the present while trying to predict what comes next. Bringing attention back to the present can help us reconnect with what is real, known, and available right now.
Making space for difficult thoughts
When people experience persistent worry, they often try to force the thoughts away. They tell themselves not to think about it. They try to distract themselves. They argue with the worry. Sometimes this works briefly. Often the thoughts return. ACT suggests a different approach. Rather than fighting thoughts, we can learn to notice them. For example:
- “I’m having the thought that my future will be unbearable”,
- “I’m noticing my mind predicting worst-case scenarios”,
- “My mind is looking for certainty again”.
This doesn’t make the thought disappear, but it can create a little more distance between ourselves and the story our mind is telling. Instead of becoming completely absorbed by the thought, we begin observing it. This creates greater flexibility in how we respond. The thought may still be present, but it no longer has to dictate our actions.
Finding stability in the present
When facing an uncertain future, many people assume they need more certainty in order to feel steadier. Yet often the opposite becomes true. The more we chase certainty, the more elusive it feels. What can sometimes provide greater stability is learning how to anchor ourselves in the present. This does not mean ignoring the future. Planning remains important. Medical decisions still need to be made. Conversations still need to happen. Practical preparations still matter. The difference is that we begin distinguishing between what can be addressed today and what currently exists only as a possibility. When there is something useful to do, we can do it. When there isn’t, we can gently redirect our attention back to the life that is unfolding right now. Sometimes that may mean noticing a conversation with a loved one. Sometimes it may mean appreciating a small moment of comfort. Sometimes it may simply mean focusing on the next hour rather than the next ten years. These moments may seem small. Yet they can provide important pockets of steadiness amidst uncertainty.
Final thoughts
One of the most challenging aspects of living with a long-term or life-limiting health condition is learning to live with unanswered questions. The future may feel unclear. There may be fears that cannot be fully resolved. There may be uncertainties that no amount of thinking can remove. This can be difficult and painful. Yet many people find that peace comes not from achieving complete certainty, but from developing a different relationship with uncertainty itself. By learning to distinguish planning from worrying, making space for difficult thoughts, and reconnecting with the present moment, it can become possible to carry uncertainty more gently. The questions about the future may still be there, but they no longer have to take up all of the space. If anxiety about the future is becoming overwhelming, therapy can offer a supportive space to explore these concerns, develop new ways of responding to worry, and find greater steadiness amidst uncertainty. You are very welcome to get in touch if that feels helpful.
