Recognizing the signs a loved one needs mental health help is one of the hardest things a family member can do, partly because the signs often appear gradually, and partly because acknowledging them means something has to change. This article walks through seven specific warning signs, plus practical guidance on what to do once you see them.
1. Withdrawal From People and Activities They Once Loved
A 2022 analysis published in JAMA Psychiatry, drawing on data from over 18,000 adults, identified social withdrawal as one of the earliest and most consistent behavioral predictors of a depressive episode, often appearing weeks before the person themselves recognizes anything is wrong. The person who used to call you every few days stops answering. The hobby they talked about constantly collects dust. The family dinner they never missed is now something they skip without explanation.
Two weeks is a reasonable threshold. If someone you care about has gone noticeably quiet, cancelled on people repeatedly, or pulled back from things that used to give them energy, reach out directly. Not a text, but a call or an in-person visit. You do not need to have the full conversation yet. Showing up is the first move.
2. Dramatic Shifts in Mood or Behavior
A 2021 study from the National Institute of Mental Health tracking 3,200 adults found that sudden, unexplained mood dysregulation, meaning emotional swings that feel disproportionate to circumstances, was present in 74% of individuals later diagnosed with a mood or personality disorder. The key word there is “unexplained.” Everyone has bad days. What you are looking for is a pattern that feels out of character over weeks, not hours.
Out of character looks like this: the person who has always been even-tempered is now erupting over small things. The optimistic one has become flat and unresponsive. Someone cries at things that would not have touched them before, or laughs at things that are not funny. These shifts are not personality flaws. They are symptoms. If you are navigating this with a teenager, the emotional intensity can be especially hard to read, but the pattern test still applies: is this new, and has it lasted more than a week or two?
3. Changes in Sleep, Appetite, or Physical Health
The American Psychological Association’s 2023 Stress in America survey of 3,185 adults found that 63% of those meeting criteria for depression or anxiety disorder reported significant physical symptoms first, before identifying any emotional distress. Sleeping 14 hours and still exhausted. Lying awake until 3am. Eating nothing for two days or eating compulsively. Headaches with no clear cause. These are not separate from mental health; they are mental health expressing itself through the body.
Watch for a sustained pattern over one to two weeks before raising it. One bad night of sleep is not a sign. A two-week stretch where someone looks physically depleted, has stopped eating meals with the family, or is barely getting out of bed is a different thing entirely. When you bring it up, lead with what you have observed physically. “You look exhausted and I’m worried” is easier to receive than a direct question about mental health.
4. Declining Performance at Work or School
A 2020 report from the World Health Organization estimated that depression and anxiety disorders cost the global economy $1 trillion annually in lost productivity, with cognitive symptoms like difficulty concentrating, memory lapses, and decision fatigue being the primary drivers. For a person in your life, this shows up as missed deadlines, dropped grades, frequent absences, or an inability to complete tasks they previously handled without effort.
When you notice this, avoid framing it as a performance problem. The most effective approach is to name what you have seen without attaching a judgment. “I’ve noticed you seem really drained lately and I’ve heard you mention work has been hard” opens a door. “You need to get it together” closes one permanently. If the person is a young adult or student, understanding how to approach these conversations with younger family members can change the outcome significantly.
5. Increased Use of Alcohol or Other Substances
The Substance Abuse and Mental Health Services Administration’s 2022 National Survey on Drug Use and Health found that 9.2 million adults in the United States had a co-occurring mental health disorder and substance use disorder, and that in the majority of cases, the substance use began as a coping strategy. This pattern escalates quickly because alcohol and many other substances temporarily suppress anxiety, numb emotional pain, and interrupt rumination, which makes them feel like solutions. They are not. They disrupt sleep architecture, deplete the neurochemicals that regulate mood, and create physical dependency, which deepens the underlying condition.
When you raise this concern, name the behavior, not the person. “I’ve noticed you’re drinking more than usual and I’m worried about you” is different from “you have a drinking problem.” The first invites a conversation. If you are unsure how to approach someone about their drinking, starting with observation and care rather than diagnosis is always the right first move.
6. Expressions of Hopelessness, Worthlessness, or Wanting to Disappear
The CDC’s 2023 National Vital Statistics Report identified expressed hopelessness as one of the strongest behavioral precursors to suicidal ideation, present in the majority of cases where a crisis event occurred. These expressions are not always dramatic. “Nothing matters anymore.” “Everyone would be better off without me.” “I’m so tired of everything.” Giving away valued possessions. Talking about being a burden. Saying goodbye in ways that feel final.
Take every one of these statements seriously, on the same day you hear them. Ask directly: “Are you thinking about hurting yourself?” Research consistently shows that asking this question does not plant the idea, it opens a door that the person may have been waiting for someone to open. If the answer is yes, or even possibly yes, act immediately. The 988 Suicide and Crisis Lifeline is available by call or text, around the clock. Do not wait for certainty before acting.
7. Loss of Touch With Reality
A 2019 study published in Schizophrenia Bulletin found that early intervention in first-episode psychosis reduced hospitalization rates by 54% and significantly improved long-term functioning outcomes. The window between first symptoms and treatment matters enormously. Psychosis-related signs include hearing or seeing things others do not, holding beliefs that seem disconnected from reality and cannot be reasoned away, or speaking in ways that do not follow a logical thread.
This is not a bad mood. It is not stress. Distinguishing between emotional distress and a break from reality is important because the response is different. If your loved one is experiencing these symptoms, contact a mental health professional or crisis line that same day. The 988 Lifeline can guide you to the right local resource. Do not try to debate or disprove what the person is experiencing; stay calm, stay close, and get professional guidance immediately.
What to Do Once You Recognize the Signs
Seeing the signs is the first step, and it is not an easy one. Acting on what you see is harder, because it requires starting a conversation you may have been avoiding and accepting that the situation needs more support than you alone can provide. The two sections below give you a direct path forward.
How to Start the Conversation
Choose a calm moment, not the middle of an argument or immediately after an incident. Sit with the person somewhere private and lead with what you have observed rather than a diagnosis. “I’ve noticed you seem really different lately and I love you, so I wanted to check in” is a starting point. Then listen more than you speak. The goal of this first conversation is not to solve anything; it is to make it safe for the person to tell you what is actually going on. If finding a treatment pathway for a family member feels overwhelming from there, that process can start with a single phone call to a behavioral health provider who can walk you through options.
When to Seek Immediate Help
Most of the signs in this article call for a prompt but scheduled response: a conversation, an appointment with a behavioral health provider, a call to a care team. But some signs require same-day action. If your loved one has expressed intent to harm themselves or others, is showing signs of psychosis, or is in a state where their safety is at immediate risk, do not wait for a scheduled appointment. Call or text 988 (Suicide and Crisis Lifeline) or go to the nearest emergency room. If there is immediate danger, call 911.
For signs that are serious but not immediately life-threatening, knowing when the situation has crossed into crisis-level territory helps you act with the right level of urgency. You do not need to have everything figured out before you make the first call. Getting on the phone with a provider today is enough.
