Supporting someone through mental illness can mean appointments, calls, medication reminders, difficult nights and constant uncertainty. It can also mean love, loyalty and a relationship that is bigger than the caring role. Caring can be meaningful and exhausting at once. Looking after yourself is part of sustaining care, not a betrayal of the person you support.
Be clear about what is and is not yours to carry
You can listen, offer practical help and encourage professional support. You cannot make another adult accept help, promise that they will never feel distressed or become their only crisis plan. The NHS advises supporters not to force someone to talk or get help, while staying available and non-judgemental. If a person is at immediate risk, use urgent local crisis or emergency services rather than trying to manage alone.
Choose language that keeps the relationship open: “I can sit with you while you call,” “I can help make a list,” or “I cannot keep talking tonight, but I can check in tomorrow.” Avoid taking responsibility for information you do not have, especially if the person is under clinical care and confidentiality limits what services can share.
Make boundaries concrete
A boundary works best when it says what you can do, what you cannot do and what happens next. Examples include setting a time when you answer non-urgent calls, sharing transport to planned appointments but not cancelling work at short notice, or asking another family member to cover one task. Start small. A boundary is not punishment and it may need to be revisited as needs change.
Write down the existing support network: clinician or service contacts, relatives, friends, community support, pharmacy, workplace support and local carer organisations. With the person's consent, agree a simple crisis plan: warning signs, preferred help, who can be called, and what to do if safety is at risk. It should not replace clinical advice or emergency care.
Your own health deserves an appointment too
Carers may notice sleep problems, resentment, guilt, anxiety, physical symptoms or loss of contact with friends. Speak to your GP if these persist or affect daily functioning. The NHS help for carers page lists carer breaks and support. In England, a carer can ask their local authority for a carer’s assessment, which considers support needs in the caring role. Availability and rights differ across the UK and internationally, so check local services.
Keep one part of the week that belongs to you, even if it is only a walk, an exercise class, a meal with a friend or quiet time without responsibility. Tell one trusted person what is happening. Carer groups can provide information and reduce the sense that you must invent every solution alone.
If the cared-for person agrees, ask their team how carers can share relevant observations and how the service communicates with families. You can give information even when confidentiality means staff cannot discuss details in return. Keep a factual note of changes, appointments and concerns if this reduces the burden of holding everything in your head.
In a crisis
If someone says they intend to harm themselves or another person, has taken an overdose, is severely confused, or cannot be kept safe, seek emergency help. Do not promise secrecy about immediate danger. If there is no immediate danger but the situation is escalating, contact the person’s care team where available or an urgent local mental-health service. You also deserve support after a crisis, even when attention has understandably focused on the person who was unwell.
