Anxiety, panic and sleeplessness during separation: what helps

Lying awake replaying the conversation. A tight chest in the car before a handover. A pounding heart in the grocery store for no reason you can name. Anxiety during a separation is not a sign that you are failing. It is a response to real uncertainty about your home, your money and your children, often all at once. And there is real help: the treatments below are recommended in US, UK and Canadian guidance.

Our wellbeing guide covers the sleep and stress basics. This piece goes further: what panic actually is, what to do in the middle of an attack, which treatment for sleeplessness has the best evidence, and when to get help.

Worry, anxiety, and when it becomes something more

Some worry during a separation is useful. It gets the documents gathered and the lawyer called. The trouble starts when it never switches off. The US National Institute of Mental Health (NIMH) notes that anxiety symptoms "are often worse during times of stress", and gives "a family or relationship conflict" as an example. For many people, worry eases as decisions are made and routines form.

Generalised anxiety disorder (GAD) is more than that. NIMH describes it as difficulty controlling worry on most days for at least six months, along with at least three of these: feeling restless or on edge, tiring easily, trouble concentrating, irritability, muscle tension and sleep problems. You do not need to wait six months or reach a diagnosis to ask for help. If worry is running your days, that is reason enough.

Panic attacks: what is actually happening

A panic attack is a sudden surge of intense fear with strong physical symptoms. NIMH lists a pounding heart, sweating, chills, trembling, difficulty breathing, dizziness, tingling, chest pain and nausea. Many people are sure, the first time, that something is badly wrong with their body.

Three facts from NIMH are worth holding on to:

• "A panic attack can last from a few minutes to an hour or sometimes longer."
• Panic attacks themselves are not life-threatening, and the physical symptoms usually pass with time.
• "An isolated panic attack is not a mental disorder." Panic disorder means repeated, unexpected attacks plus at least a month of worrying about more attacks or changing what you do to avoid them.

If you have never had an attack before, or you have chest pain or trouble breathing, get checked by a doctor so physical causes can be ruled out, which NIMH also advises. If you are not sure whether it is your heart, call 911.

What to do during a panic attack

1. Name it. Say to yourself: "This is panic. It is horrible, and it will pass."
2. Slow the out-breath. Breathe in gently for a count of two, pause, then breathe out slowly for a count of three, four, five, and pause again. Make the out-breath longer than the in-breath, and repeat.
3. Stay put if you safely can. Sit down, put your feet flat on the floor, and let the wave rise and fall. Leaving in a hurry can teach your brain that the place was dangerous.
4. Ground yourself. Name five things you can see and three you can hear.
5. Afterwards, do something ordinary. Finish the shopping, make the tea. It tells your body the emergency is over.

CBT for panic works partly by helping people face, step by step, the sensations and situations they have started to avoid. NIMH describes CBT, including this kind of exposure work, as the "gold standard" psychotherapy for panic disorder.

Sleep: when a few bad nights become insomnia

Short-term sleeplessness after a shock is very common. The basics in our wellbeing guide (the same wake-up time every day, the bed kept for sleep, the phone out of the room) are the right place to start. But if poor sleep has gone on for months, tips are usually not enough on their own.

The American Academy of Sleep Medicine's 2021 guideline strongly recommends multicomponent cognitive behavioural therapy for insomnia (CBT-I) for adults with chronic insomnia. The same guideline suggests clinicians do not use sleep hygiene advice as a treatment on its own. Sleep hygiene is a set of good habits. CBT-I is the treatment.

How well does it work? A 2015 meta-analysis of 20 randomised trials with 1,162 adults with chronic insomnia found that, after face-to-face CBT-I, people fell asleep about 19 minutes faster, spent about 26 minutes less time awake during the night, and the share of time in bed actually spent asleep rose by about 10 percentage points. The change in total sleep time was small and uncertain. The benefits seemed to last, and no harms were reported. Canada's CANMAT depression guidelines (2023) also describe early, promising results for CBT-I in people with depression.

What CBT-I involves

The guideline names several parts that can be used alone or together:

• Stimulus control: using the bed only for sleep, and getting up if you have been lying awake for a long time, so your brain relearns that bed means sleep.
• Sleep restriction: temporarily limiting time in bed to roughly the time you actually sleep, then extending it as sleep improves. This is best done with a clinician or a structured program, because it can make you more tired at first.
• Relaxation: methods to calm the body before bed.
• The thinking part: working on the worries about sleep itself ("If I don't sleep, I'll fall apart at the mediation") that keep you awake.

Ask your doctor or a therapist about CBT-I by name. It is offered in person, by phone, in groups and in structured online programs.

Sleeping pills and a nightcap

When you are desperate for sleep, medication can be tempting. NIMH notes that benzodiazepines (a group of sedatives sometimes prescribed for anxiety) can work quickly, but because of tolerance and dependence they may be prescribed only for brief periods. UK guidance (NICE) advises they should not be prescribed for panic disorder, because they are linked to a poorer long-term outcome, and for generalised anxiety only as a short-term measure in a crisis. Talk this through with your prescriber, and never stop a prescribed medicine suddenly without advice.

Alcohol is the other common sleep aid. Canada's Guidance on Alcohol and Health lists better sleep among the benefits of not drinking. Our guide to alcohol and other coping that backfires has alternatives.

Treatment that works for anxiety and panic

NIMH describes CBT as the "gold standard" psychotherapy for both generalised anxiety and panic, and says that with the right treatment and support, people can manage their symptoms and improve their quality of life. UK guidance (NICE) sets out a stepped approach:

• Start with information and monitoring.
• Next, low-intensity help such as guided self-help based on CBT, or a psychoeducational group.
• Then, if needed, individual CBT, applied relaxation, or medication. For generalised anxiety, NICE says to choose based on your preference, as there is no evidence that one of these is better than the other.

For panic disorder, NICE notes that "psychological therapy, medication and self-help have all been shown to be effective."

Your anxiety and your children

Children are experts at reading their parents' faces. The Harvard Center on the Developing Child notes that significant stress, such as money worries or a lack of social connection, can make it harder for adults to respond warmly to young children. That is not a reason for guilt. It is a reason to treat your own anxiety as part of caring for them.

You do not need to hide every wobble. Showing a child how you calm down is a useful lesson.

Older children and teenagers will pick up on legal and money worries. Keep the details with the adults.

If handovers are the flashpoint, plan them like a routine: same time, same place, short and friendly. Our guide to handovers without tears has a step-by-step approach.

If you are afraid of your ex. Shared communication, handovers and joint plans may not be safe where there has been family violence, threats or coercive control. Your safety, and your children's, comes before any co-parenting advice here. Read separating safely when there is abuse and make a safety plan. Press Shift+Esc to leave this site quickly.

Try this tonight

• Empty your head onto paper. Write each worry down, then next to it write one small next step, or "can't act on this tonight." Close the notebook.
• Give worry a set time. Fifteen minutes in the early evening to think it through, so that at 3 a.m. you can tell yourself, "That's for tomorrow's worry time."
• Practise the slow breathing once while you are calm, so it is familiar when you need it.
• Silence messages from your ex after a set hour, using your phone's do-not-disturb setting, and choose a time tomorrow to read them.
• If you are lying awake for a long time, get up. Sit somewhere dim and do something dull until you feel sleepy, then go back.
• Set one alarm for the same time tomorrow, however the night goes.
• Skip the nightcap.

When to get help

• Worry or panic is stopping you working, driving, parenting or leaving the house.
• You are avoiding places or people because you fear another attack.
• Poor sleep has lasted more than a few weeks and is getting worse.
• You are using alcohol, cannabis or pills you were not prescribed to calm down or to sleep.
• Anxiety is mixed with hopelessness, or thoughts of death or suicide. Please read our guide to depression after separation, and reach out now: call or text 9-8-8 in Canada or 988 in the US, any time.
