Low Mood, Sadness, & Depression

Feeling sad, heavy, or low is part of being human. Sometimes those feelings pass. Other times, they linger, deepen, or begin to affect how you think, feel, and function day to day.

You can learn more below. Note that this is not for diagnosis.  It’s to help you learn about sadness, low mood, and depression, as wells options for coping and feeling better. Disclaimer: 3rd party videos for educational purposes only. May contain ads.

What This Can Feel Like

People experience low mood and depression in many different ways.

You might notice:

  • Persistent sadness, emptiness, or heaviness

  • Loss of interest or pleasure in things you used to enjoy

  • Feeling tired, slowed down, or unmotivated

  • Difficulty concentrating or making decisions

  • Changes in sleep or appetite

  • Feelings of guilt, worthlessness, or hopelessness

  • Irritability or emotional sensitivity

  • Wanting to withdraw from people or responsibilities

Not everyone feels “sad.” Some people describe feeling numb, flat, or disconnected instead.

You’re not weak, broken, or failing if you relate to some or all parts of this description.

Why Low Mood Can Happen

Low mood and depression are rarely caused by one single thing.

They often reflect a combination of:

  • Ongoing stress or burnout

  • Trauma or cumulative emotional strain

  • Loss, grief, or major life transitions

  • Chronic sleep problems

  • Physical health issues or pain

  • Social isolation

  • High-responsibility or high-risk work environments

For people in helping or high-stress professions, low mood may show up gradually – sometimes after years of “pushing through.”

Lifestyle Basics That Can Help

Developing and practicing healthier lifestyle habits can positively impact your mood.

While these things can seem basic, they aren’t always easy to do, especially if you have a lot of demands on you or struggle to stay motivated.

  • Sleep – Sleep has a direct effect on mood. Set yourself up for the best quality sleep you can – even if your schedule varies a great deal.

  • Movement – Movement, whether or not it is in the form of “exercise,” can improve mood. Consider how you can harness the power of movement without making it too complicated or time-consuming.

  • Eating – Diet affects mood by influencing brain chemistry, energy levels, and inflammation. Foods that cause blood sugar spikes and crashes can fuel irritability and depression. Take steps to increase food choices that support stable moods.
  • Alcohol – While alcohol can initially enhance positive feelings and lower inhibitions, it disrupts mood-regulation over time, which tends to worsen sadness and anxiety. If you drink, explore how drinking less improves your mood.
  • Connection – Social connection can help overcome a sense of isolation. It can also help you access practical and emotional support from others.

Keep in mind that everyone’s personality, lifestyle, experiences, and preferences are different.  If one approach doesn’t help, that doesn’t mean nothing will. Don’t give up on feeling better, even if you try some things and don’t feel better.

Sadness or Depression?

Sadness and depression are not the same thing.

Sadness is a natural emotional response to loss, disappointment, stress, or difficult life events. It usually comes and goes, even if it feels intense.

Depression involves patterns that tend to:

  • Last longer (weeks or months)

  • Affect multiple areas of life (work, relationships, health)

  • Change how you think about yourself, others, or the future

  • Make it harder to function or feel relief

Depression-Related Disorders

The Diagnostic and Statistical Manual 5 (DSM5) lists a number of disorders with low or depressed mood being the primary symptom. These conditions also involve ongoing nervous system hypoarousal. Click on the + to learn more about some of them.

Involves feeling persistently sad, empty, or losing interest in activities is common in this disorder. It is diagnosed when a person experiences a depressed mood or loss of interest or pleasure in most activities for at least two weeks and symptoms such as changes in sleep or appetite, fatigue, difficulty concentrating, feelings of worthlessness or excessive guilt, and recurrent thoughts of death or suicide. Milder forms involve symptoms that are distressing, but manageable in daily life. When severe, it significantly impairs social, occupational, or educational functioning.
Involves a chronic low mood that lasts for years and can subtly affect daily life. Clinically, it is defined by a depressed mood lasting at least two years in adults (one year in children/adolescents), often accompanied by low energy, poor self-esteem, difficulty concentrating, and disturbances in sleep or appetite. Symptoms may be less intense than Major Depressive Disorder but are longer lasting and can coexist with occasional major depressive episodes.
Involves significant mood changes in the week before their period that interfere with daily life. Clinically, PMDD is defined by depressive symptoms, irritability, or anxiety occurring in the luteal phase of the menstrual cycle, remitting shortly after menstruation begins, and causing substantial impairment in work, social activities, or relationships. Symptoms are more severe than those associated with typical premenstrual syndrome (PMS).

Involves significant mood changes in the week before their period that interfere with daily life. Clinically, PMDD is defined by depressive symptoms, irritability, or anxiety occurring in the luteal phase of the menstrual cycle, remitting shortly after menstruation begins, and causing substantial impairment in work, social activities, or relationships. Symptoms are more severe than those associated with typical premenstrual syndrome (PMS).

Some individuals experience depressive symptoms that do not fully match any specific diagnosis but still cause distress or impairment. Clinically, “Other Specified Depressive Disorder” is used when a clinician indicates why criteria are not met (e.g., short-duration depressive episodes), whereas “Unspecified Depressive Disorder” is used when the clinician chooses not to specify the reason. Both ensure that subthreshold or atypical depressive

Some people experience depressive symptoms that predictably emerge during certain times of the year, most often in the fall or winter months. Clinically, SAD is used to depressive episodes that occur as part of major depression or mood conditions that include both low and elevated mood states. Symptoms are otherwise consistent with major depression and may include low mood, low energy, changes in sleep or appetite, and reduced functioning, with symptom improvement during other seasons.

Some individuals experience periods of low mood that alternate with times when their mood is abnormally high or irritable. They may feel unusually energetic, talkative, restless, or impulsive, and may engage in activities more intensely than usual. This may follow a seasonal pattern.

When this creates distress or interferes with functioning, a bipolar disorder may be diagnosed. Clinically, these disorders are diagnosed on a spectrum:

  • Bipolar I – episodes of elevated or irritable mood with increased energy and activity (mania), often alternating with depressive episodes.
  • Bipolar II – less intense periods of elevated mood (hypomania) with major depressive episodes.
  • Cyclothymic Disorder – involves chronic, variable periods of mild low mood and elevated mood that don’t meet all criteria for both major depressive or hypomania. The pattern must have lasted at least two years in adults or one year in children/adolescents.

Depressive episodes in these conditions meet criteria for Major Depressive Disorder, but treatment and monitoring differ from unipolar depression because of the presence of these alternating elevated or irritable states. Accurate recognition is essential for diagnosis, safe treatment, and long-term support.

In this video, Dr. Tracy Marks explains the connection between depressive symptoms and bipolar spectrum disorders.
