Mental health can affect how a person thinks, feels, behaves, and handles everyday life. Mental health symptoms can appear in many different ways, and not everyone experiences them in the same way. Changes in mood, sleep, energy, thinking, or behavior may be signs that someone needs additional support.
A difficult day does not always mean someone has a mental health condition. However, symptoms that continue, become more severe, or interfere with daily activities may be worth discussing with a healthcare professional. SAMHSA suggests seeking help when changes in thoughts, moods, or physical well-being make it difficult to manage work, school, home, or relationships, especially when they continue for two weeks or more.
Changes in Mood and Emotions
One of the most noticeable signs can be a lasting change in mood. A person may feel unusually sad, worried, hopeless, angry, irritated, or emotionally overwhelmed. They may also lose interest in hobbies or activities they once enjoyed.
Depression, for example, can involve sadness, hopelessness, irritability, low energy, loss of interest, and difficulty concentrating. These symptoms can affect everyday responsibilities and relationships.
Occasional sadness or stress is a normal part of life. The concern is when emotional changes last, become difficult to manage, or begin affecting normal activities.
Changes in Sleep
Sleep can also provide clues about mental well-being. Some people may have trouble falling asleep, wake up too early, or sleep much more than usual. Changes in sleep can occur with several mental health conditions, but they can also have physical causes.
For this reason, ongoing sleep problems should not automatically be viewed as a mental health diagnosis. A healthcare professional can help identify possible causes and decide whether further evaluation is needed.
Changes in Energy and Motivation
A person experiencing mental health difficulties may feel unusually tired or have very little motivation. Simple tasks can begin to feel difficult. Someone may stop keeping up with household responsibilities, work, school, personal care, or social activities.
Low energy can have many causes, including physical illness, medication effects, poor sleep, stress, or mental health conditions. Looking at other symptoms and how long the changes have lasted can help provide a clearer picture.
Difficulty Thinking or Concentrating
Mental health problems can sometimes affect concentration, memory, and decision-making. Someone may have trouble focusing on a conversation, completing normal tasks, remembering appointments, or making simple decisions. NIMH lists difficulty concentrating, remembering, or making decisions among symptoms that can occur with depression and other mental health concerns.
If these problems are new or interfere with daily life, talking with a healthcare professional can be helpful.
Changes in Appetite or Physical Health
Mental health symptoms are not always emotional. Changes in appetite or weight can occur along with mood changes. Some people may eat much more or much less than usual. Others may experience headaches, stomach problems, aches, or other physical symptoms without a clear explanation.

NIMH notes that some mental health conditions can involve physical symptoms, but medical conditions can also produce similar changes. A healthcare provider can help determine what may be causing them.
Pulling Away From Others
Social withdrawal is another change worth noticing. A person may stop contacting friends, avoid family gatherings, or spend much more time alone. They may lose interest in activities they normally enjoy or find it difficult to maintain relationships.
Social withdrawal can happen for many reasons, including stress, grief, depression, anxiety, or other concerns. When it continues alongside other changes, it may be a reason to seek professional support.
Unusual Changes in Behavior
Changes in behavior can sometimes be easier for family members or friends to notice than changes in mood.
These may include:
- Increased irritability or anger
- Loss of interest in normal activities
- Neglecting personal care
- Increased alcohol or drug use
- Taking unusual risks
- Sudden changes in social behavior
- Difficulty meeting normal responsibilities
NIMH notes that changes in behavior, sleep, self-care, social activity, and work or school performance can occur with serious mental health conditions. A sudden or severe change should be taken seriously, particularly when it continues or becomes worse.
Changes in Thoughts or Perception
Some symptoms involve changes in the way a person thinks or experiences the world. A person may become unusually suspicious, have difficulty thinking clearly, or struggle to distinguish reality from imagination. Hallucinations and delusions can occur during psychosis and require professional evaluation.
These symptoms should not be ignored. Early professional support can help identify the cause and determine appropriate treatment.
When Should You Seek Professional Help?
There is no need to wait until symptoms become severe before asking for help.
Consider speaking with a healthcare professional when symptoms:
- Continue for two weeks or longer
- Interfere with work, school, or relationships
- Make daily tasks difficult
- Keep getting worse
- Cause significant distress
- Lead to increased alcohol or drug use
- Cause major changes in behavior or thinking
NIMH recommends professional help for severe or distressing symptoms that last two weeks or more, particularly when they interfere with normal activities.
A primary care provider can be a starting point and may refer someone to a psychologist, psychiatrist, clinical social worker, or another qualified professional.
What If Someone Is in Crisis?
Some mental health symptoms require immediate attention. If someone talks about wanting to die, feels there is no reason to live, makes a suicide plan, gives away important belongings, or shows other serious warning signs, seek help immediately. NIMH recommends getting help as soon as possible when these warning signs appear.
In the United States, people experiencing a mental health or suicide crisis can call or text 988 for the Suicide & Crisis Lifeline. In a life-threatening emergency, call 911.
Recognizing Symptoms Is the First Step
Recognizing changes in mood, sleep, energy, thinking, behavior, and daily functioning can help people know when it may be time to seek support. These signs do not automatically mean that someone has a specific mental health disorder, but persistent or worsening changes deserve attention.
Professional evaluation can help identify what is happening and whether treatment or other support may be useful. Mental health care can include therapy, medication, or a combination of approaches depending on the person’s needs.
