Stress vs. something more

Stress usually comes from something outside you, like a test or a fight, and fades once it's handled. Anxiety and depression are different: they stick around, show up without a clear cause, and get in the way of sleep, work, school or relationships. NIMH's line: if severe or distressing symptoms last two weeks or more, talk to a professional. Here's how to tell the difference and what to do either way.

What to know

Name the source. Stress is a response to something outside you, like a big test, an illness or an argument, and it generally goes away once the situation is resolved. Source: NIMH¹ It can even help, like pushing you to meet a deadline. Source: NIMH¹
Notice if it's sticking. Anxiety is your body's reaction to stress, and it can happen even when there's no current threat. It usually involves a persistent sense of dread that doesn't go away and interferes with your life. Source: NIMH¹
Check for warning signs. You may be at risk for an anxiety disorder if stress symptoms interfere with everyday life, make you avoid things, or seem to be always there. Source: NIMH¹
Check for depression. Common signs include a persistent sad, anxious or "empty" mood, hopelessness, losing interest in things you used to enjoy, fatigue, trouble concentrating, sleeping too little or too much, appetite changes, and thoughts of death or suicide. Source: NIMH² It can also look like irritability, pulling away from people or drinking more. Source: NIMH²
Use the two-week rule. Seek professional help if severe or distressing symptoms have lasted 2 weeks or more, like trouble sleeping, trouble getting out of bed because of your mood, losing interest in things you enjoy, or not being able to do your usual tasks. Source: NIMH³
Either way, take care of the basics. Just 30 minutes of walking a day can boost your mood, and small amounts add up. Eat regular meals, drink water, watch caffeine and alcohol, keep a sleep schedule and cut screens before bed. Source: NIMH³
Tell someone. Reach out to friends or family who help you cope in a positive way. Source: NIMH¹ If you're worried, start with a primary care provider, who can refer you to a mental health professional. Source: NIMH³

Watch out If you're thinking about suicide or in emotional distress, call or text 988, or chat at 988lifeline.org. It's free, confidential and available 24/7. In a life-threatening situation, call 911. Source: NIMH³

If it doesn't work

Not sure it's "bad enough"? You don't need every symptom. People with only a few symptoms may still benefit from treatment. Source: NIMH²
Worried it's just you being weak? Depression isn't ordinary sadness that passes. It can cause severe symptoms that affect how you feel, think, sleep, eat and work, and it can affect anyone. Source: NIMH² It's treated like any other health problem: talk therapy, medication or both are the usual treatments, and finding the right fit can take trial and error. Source: NIMH²
Worried about a friend? If you see signs of depression in someone, encourage them to get help from a mental health professional. Source: NIMH² Try: "You haven't seemed like yourself lately. I'm worried about you. Want to talk, or want help finding someone?"
Stressed by too much at once? Decide what has to get done now and what can wait, and learn to say no to new tasks when you're overloaded. Source: NIMH³
In school? Your campus counseling center is often the fastest door in. See Using campus counseling.

Good to know

The details, if you want them. Tap a line to open it.

Stress or anxiety, side by side

Stress: usually a reaction to an outside cause, and it fades when that's resolved. Anxiety: internal, persistent and there even without an immediate threat. Both can cause worry, tension, headaches, high blood pressure and lost sleep. Source: NIMH¹

What GAD is

Generalized anxiety disorder means finding it hard to control worry on most days for at least 6 months, plus symptoms like restlessness, fatigue, trouble concentrating, irritability, muscle tension or sleep problems. Source: NIMH⁴ It often starts in early adulthood. Source: NIMH⁴

What depression is

A diagnosis of depression means symptoms most of the day, nearly every day, for at least 2 weeks, including a low mood or loss of interest in most activities. Source: NIMH²

Men and depression

Men may be less likely to recognize, talk about or seek help for negative feelings, so their depression is more likely to go undiagnosed. Source: NIMH²

A quick self-check

In the past two weeks: Am I sleeping much more or less than usual? Have I stopped enjoying things I used to like? Am I avoiding people, classes or work? Am I drinking or using more to cope? Does it feel like it won't get better? Two or more yeses, or any thoughts of not wanting to be here, is a reason to talk to someone this week.
