- Changes in sleep, energy, appetite and concentration are common signs that are easy to blame on a busy life.
- Physical symptoms such as headaches or digestive problems without a clear cause can be part of depression.
- Men, teens, children and older adults may each show depression differently.
- Signs that last most of the day, nearly every day, for at least two weeks are a reason to talk with a professional.
Why depression gets missed
Most people picture depression as someone who is visibly sad and tearful. That picture is real, but it is only one version. Depression is a mood disorder that affects how a person feels, thinks and handles daily activities, and it can look quite different from one person to the next.
It also tends to arrive gradually. A shorter temper, a skipped hobby, a few bad nights of sleep: each one has an ordinary explanation. It is often the pattern, not any single change, that tells the story. Knowing the quieter signs makes the pattern easier to see in yourself or in someone you love.
The quieter signs
The National Institute of Mental Health lists a persistent sad, anxious or empty mood among the signs of depression. It also lists a number of signs that many people would not connect with depression at all.
- Irritability or anger: some people seem angry or irritable instead of sad
- Loss of interest: hobbies, plans and people that used to matter start to feel like a chore
- Sleep changes: trouble sleeping, waking too early in the morning, or oversleeping
- Low energy: fatigue, or a sense of being slowed down
- Trouble thinking: difficulty concentrating, remembering or making decisions
- Appetite changes, or weight changes you did not plan
- Guilt: feeling worthless or helpless, or being very hard on yourself
- Pulling away from other people
When it shows up in the body
Depression is not only in the mind. It can appear as physical problems such as a racing heart, a tight chest, ongoing headaches or digestive issues. Aches, headaches or stomach trouble without a clear cause are on the list of symptoms to notice.
This is one reason depression goes unrecognized. A person may see a health care provider about the physical symptoms and never mention how they have been feeling. Physical symptoms deserve a medical check in their own right. It also helps to tell your provider about your mood, sleep and energy, so they have the whole picture.
How it can look in men, teens and others
Depression looks different for everyone, and a few patterns are worth knowing.
In men, signs can include anger, irritability or aggressiveness, feeling flat or having trouble feeling positive emotions, engaging in high-risk activities, and physical complaints. An increase in alcohol or drug use can also be a warning sign to raise with a doctor. Men may be less likely to seek help for emotional symptoms, so the people around them are often the first to notice a change.
In teens, depression can be mistaken for ordinary moodiness. Signs include being easily frustrated, irritable or angry, pulling away from friends and family, dropping grades, and changes in eating or sleeping. Teens may also sleep much more than usual.
Children may seem anxious or cranky, pretend to be sick, refuse to go to school or cling to a parent. Older adults may describe a lack of emotion more than a low mood, and their signs can be less obvious.
When to get help
Everyone has off days, so timing matters. To be diagnosed with depression, a person must have symptoms most of the day, nearly every day, for at least two weeks. A web page cannot diagnose you. If the signs here sound familiar and they are not going away, talk with a health care provider or a mental health professional.
Depression is typically treated with talk therapy, medication or both. Medication decisions belong with a prescriber. Small daily steps can support treatment as well: some physical activity, a regular sleep schedule, regular meals, and time with people you trust.
Some signs need help right away. If you or someone you know is thinking about death or suicide, call or text 988, or call 911 in a life-threatening situation. Locascio Wellness does not provide emergency services. Our crisis resources page lists more options.
How we can help
Therapists on our team work with children from age 7, teens and adults living with depression, using approaches such as cognitive behavioral therapy, person-centered therapy, solution-focused therapy and mindfulness-based approaches. Not every therapist uses every approach, so we match you with someone who fits. You can read more on our depression therapy page, and parents may find the teen therapy page useful. If worry is a big part of the picture, see anxiety therapy.
All sessions are online, by secure video, for people who are physically located in Pennsylvania, West Virginia or Arizona during the session. We do not prescribe medication.
A free 15-minute consultation is an easy first step, and you can book one online. Our insurance and fees page explains coverage. Noticing the signs is the hard part. Things can get better from here.
Common questions
Can you be depressed without feeling sad?
Yes. The National Institute of Mental Health notes that people may show symptoms other than sadness, such as seeming angry or irritable. Others notice mostly a loss of interest, low energy, poor sleep or trouble concentrating. Some describe feeling flat or empty. If changes like these last most days for two weeks or more, they can be signs of depression.
Can depression cause physical symptoms?
It can. Depression may appear as physical problems such as a racing heart, a tight chest, ongoing headaches or digestive issues, along with fatigue and changes in sleep and appetite. Physical symptoms should always be checked by a medical provider. It helps to mention your mood and energy at the same visit, so nothing is overlooked.
How is depression different in men?
Men can have the same symptoms as anyone else, but the signs are sometimes less expected: anger, irritability or aggressiveness, feeling flat, taking more risks, or physical aches without a clear cause. Men may also be less likely to seek help for emotional symptoms. A change in temper or habits that lasts is worth a conversation.
How do I know if my teen is depressed or just moody?
Look for a lasting change, not one bad week. Signs in teens include being easily frustrated, irritable or angry, pulling away from friends and family, dropping grades, and changes in sleep or eating. Ask your teen directly how they have been feeling, and talk with their doctor or a therapist if you are concerned.
When should I see a therapist about depression?
If signs of depression persist or do not go away, it is time to talk with a professional. You do not need to wait until things are severe. At Locascio Wellness, a free 15-minute consultation comes before a first session, and sessions are by secure video. If you are in crisis, call or text 988 or call 911 instead.
