A mental health crisis is any situation in which a person's thoughts, feelings, or behavior put them at risk of harming themselves or others, or leave them unable to function or stay safe. Warning signs include talk of suicide or hopelessness, sudden withdrawal, extreme mood changes, and loss of touch with reality. If you or someone you know shows these signs, help is available immediately by calling or texting 988.
When to Seek Medical Care
Call 911 or go to the emergency room immediately if you or someone you know:
- Is talking about wanting to die or having thoughts of suicide with a plan, means, or intent, call or text 988 (US) (Suicide & Crisis Lifeline) or chat at 988lifeline.org; call 911 if there is immediate danger
- Has attempted self-harm or has visible injuries from self-harm
- Is expressing intent to harm someone else, or is behaving in a way that threatens others' safety
- Is experiencing a break from reality, hallucinations, delusions, or extreme confusion that puts them in danger
- Has taken more than the prescribed amount of a medication or ingested drugs or alcohol along with pills (possible overdose), call Poison Control at 1-800-222-1222 (US) or go to the ER
- Is unable to care for their own basic safety, such as wandering into traffic or being unaware of their surroundings
See a doctor or reach out for support soon (not an emergency) if you have:
- Persistent low mood, hopelessness, or loss of interest without any thoughts of suicide or self-harm
- Growing withdrawal from friends, family, work, or activities you used to enjoy
- Difficulty sleeping, eating, or functioning day to day that has lasted more than a couple of weeks
- A loved one whose behavior worries you but who is not in immediate danger, a call to 988 can help you figure out next steps even when you are calling for someone else
What Counts as a Mental Health Crisis
A crisis is not always as dramatic as it sounds. It can be a quiet, private moment when someone feels they cannot go on, or it can be a sudden, visible break in how a person thinks or behaves. What defines a crisis is risk, either to the person's own safety or to someone else's, combined with a loss of the person's usual ability to cope. Crises can build slowly over weeks of worsening depression or anxiety, or they can appear suddenly after a loss, a trauma, a relapse in substance use, or a change in medication.
Early Warning Signs to Watch For
Crises rarely come out of nowhere. Family, friends, and coworkers are often in the best position to notice changes before things escalate. Signs worth paying attention to include:
- Talking about feeling hopeless, trapped, or like a burden to others
- Withdrawing from people, canceling plans, or going quiet on communication
- Sudden calm after a period of severe depression, which can sometimes signal a decision has been made
- Giving away possessions or making final arrangements
- Increased use of alcohol or drugs
- Extreme mood swings, from despair to agitation or rage
- Reckless behavior, as if there is nothing left to lose
- Changes in sleep or appetite that come on quickly and severely
- Talking, writing, or posting online about death or dying
No single sign confirms a crisis on its own, but a combination of these changes, especially a sudden shift, is worth taking seriously.
High-Risk Warning Signs That Need Immediate Action
Some signs point to imminent danger and should never be waited out. These include direct statements about wanting to die, researching or acquiring a method, saying goodbye to people, or describing a specific plan. Access to lethal means, such as firearms or a stockpile of medication, sharply increases risk during a crisis, and removing or securing that access, even temporarily, is one of the most protective steps a family member can take while help is arranged.

How to Support Someone in Crisis
Stay calm and listen without judgment. Ask directly whether the person is thinking about suicide, this does not plant the idea and often brings relief that someone noticed. Avoid leaving the person alone if you believe they are at immediate risk, and remove or secure access to firearms, medications, or other means of self-harm where possible. Help them connect to 988 or a crisis team rather than trying to manage the situation entirely on your own, and follow up in the days after a crisis, since risk often remains elevated even after the immediate danger has passed.

- A sudden calm after severe depression can be a warning sign, not a relief

Frequently Asked Questions
What is the difference between a bad day and a mental health crisis?
A bad day involves low mood or stress that you can still manage and that passes with rest, support, or time. A mental health crisis is a situation where someone's thoughts, feelings, or behavior put them at risk of harming themselves or others, or leave them unable to function or care for themselves safely. The presence of thoughts of suicide, self-harm, or a loss of touch with reality is what separates a crisis from ordinary distress.
Is 988 only for suicidal thoughts?
No. The 988 Suicide and Crisis Lifeline is for any mental health, substance use, or emotional crisis, not only active suicidal thoughts. You can call or text 988 if you are overwhelmed, panicking, worried about a loved one, or simply need to talk to someone right away.
What happens if I call 988?
A trained crisis counselor answers, listens without judgment, and helps you work through what you are feeling. In most cases the call ends with a safety plan and referrals to local support. Emergency dispatch is only used in the small number of cases where someone is in immediate, life-threatening danger and cannot be kept safe another way.
Can I get help if the person in crisis refuses to talk to anyone?
Yes. You can call 988 or a local crisis line yourself for guidance on how to approach the situation, even if the person will not engage directly. Many communities also have mobile crisis teams that can respond in person to assess someone who is unwilling to seek help on their own.
Does calling a crisis line cost money?
No. 988, the Crisis Text Line, and the SAMHSA National Helpline are all free and confidential, and they are available by phone, text, or chat 24 hours a day, 7 days a week.
