Is it normal to feel low or anxious with heart failure?

Yes - it is very common and understandable given the symptoms, uncertainty and lifestyle changes, and it is treatable. It is worth telling your team, because addressing low mood or anxiety also helps you keep up the self-care that heart failure depends on.

Could my tiredness and poor sleep be depression or just the heart failure?

It can be either or both - the symptoms overlap. That is exactly why it is best to discuss it with your team rather than assume: some symptoms may be the heart, some the mood, and both can be helped.

Can anxiety make my breathlessness worse?

Yes. Anxiety and breathlessness feel similar and can feed each other - breathlessness triggers panic, which worsens the breathlessness. Calming techniques help, but new or worsening breathlessness should still be checked (see the flare-up guide).

Where do I turn if I feel I cannot cope?

Call 995 if you are in immediate danger; otherwise the Samaritans of Singapore (SOS) are on 1767 and mindline.sg on 1771, any time, and you should speak to your doctor. The Institute of Mental Health provides specialist care.

Heart Failure and Mental Health: Coping and Support (Singapore)

Written & reviewed by the BestDoctors.sg editorial team · Last updated 29 Aug 2026 · General information, not medical advice

Quick answer. Living with heart failure is hard emotionally as well as physically, and low mood, depression and anxiety are common, understandable and treatable – not a personal failing. They matter medically, because they can affect self-care, so they are worth addressing. A key point: several heart failure symptoms (fatigue, poor sleep, breathlessness) overlap with depression, and anxiety and breathlessness feel similar and can feed each other – so it is best to discuss changes with your team rather than self-diagnose. Support helps: talking therapies, cardiac rehab, peer support. If you ever feel unable to cope or have thoughts of self-harm, reach out now: SOS 1767, mindline.sg 1771, or 995 in an emergency. This is general information, not a diagnosis.

The emotional side of heart failure

Living with heart failure is hard both physically and emotionally. Breathlessness, fatigue, limits on activity, uncertainty about the future, hospital visits and changes to your life and medicines all take a toll. In that context, low mood, depression, anxiety and worry are common, understandable and treatable – not a personal failing or a sign of weakness. Being told you have a heart condition can be frightening and cause real stress. Recognising these feelings as a normal response to a genuinely difficult situation is the first step, and it opens the door to support that works. Looking after your mental health is part of managing heart failure, not separate from it.

Why it matters medically

Depression and anxiety are more common in people with heart failure than in the general population, and they are not just an emotional issue – they matter medically. Low mood and anxiety can undermine the self-care that heart failure depends on: taking medicines, weighing daily, staying active, managing salt and fluid. Because of this, they are linked with poorer outcomes and more hospital admissions. So mood is something to address, not dismiss. The encouraging flip side is that treating mood often helps people engage with their heart care, and managing the heart failure well – fewer symptoms and crises – often lifts mood. The two run together.

The symptom-overlap trap

Here is a subtle but important point. Several heart failure symptoms – fatigue, poor sleep, breathlessness, low energy, reduced appetite – overlap with the symptoms of depression, and severe anxiety and breathlessness feel similar and can feed each other (breathlessness triggers panic, which worsens the breathlessness). This overlap means it can be genuinely hard to tell what is the heart and what is the mood – and often it is both. That is exactly why it is worth discussing changes with your heart failure team rather than self-diagnosing: they can help work out which symptoms are the heart, which are mood, and how to treat each, since both are treatable.

What helps

Several things help. Talk to your team early – your GP, cardiologist or heart failure nurse – and ask them to help sort out whether symptoms are the heart, the mood, or both. Talking therapies, such as counselling or cognitive behavioural therapy, help with low mood, worry and health anxiety. Cardiac rehabilitation supports emotional wellbeing as well as fitness, and offers contact with others. Peer support – meeting others living with heart conditions – reduces isolation. Keeping gentle routines, staying socially connected, and involving family all help. And never stop or change your heart failure medicines because of mood or side-effect worries without speaking to your team first.

Support for carers

It is not only the person with heart failure who feels the strain. Carers and family members caring for someone with a fluctuating, sometimes frightening condition carry a real emotional and practical load, and they need support too. Seeking their own support, sharing the caring where possible, and taking respite are not indulgences but ways of sustaining care over the long term. Involving family in appointments and in the action plan also helps everyone feel more prepared and less alone. If you are a carer feeling overwhelmed, the same support routes and crisis lines in this guide are there for you as well.

If you are struggling – reach out now

If you ever feel unable to cope, hopeless, or you have thoughts of harming yourself, please reach out straight away – you deserve support and do not have to face this alone. In Singapore, the Samaritans of Singapore (SOS) are on 1767 and mindline.sg is on 1771, both around the clock. In an emergency or immediate danger to life, call 995 or go to the nearest A&E. For ongoing specialist mental-health care, speak to your doctor or the Institute of Mental Health (IMH), and hospital medical social workers can help with practical and financial support. Reaching out is a sign of strength.

Support in Singapore

Your heart failure team is a good first point of contact and can refer you for psychological support, to medical social workers, and to cardiac rehabilitation. For specialist mental-health care, a GP or polyclinic can refer you, and the Institute of Mental Health provides specialist services. For peer and emotional support, the Singapore Heart Foundation runs a Healthy Heart Support Group, and the Heart Failure Society (Singapore) and the Heartlanders programme offer heart-failure-specific support. Combining medical care for your heart, treatment for your mood, and the understanding of people who have been there addresses both sides of living with heart failure.

General information only. This guide supports, but does not replace, advice from your own doctor and heart failure team, and your own care plan always comes first. Call 995 or go to A&E for severe or sudden breathlessness, breathlessness at rest or that stops you lying down at all, chest pain, coughing up pink frothy spit, fainting, or blue lips – these can be a medical emergency. Contact your heart failure team or doctor promptly if you have a rapid weight gain over a few days, increasing swelling, or worsening breathlessness, as these can mean fluid is building up. Never start, stop or change your heart failure medicines without medical advice, and avoid anti-inflammatory painkillers unless your doctor says they are safe for you. Weigh yourself and follow any fluid or salt limits as your own team has advised. If you are struggling emotionally, the Samaritans of Singapore (SOS) are on 1767 and mindline.sg on 1771.
