Oct. 9 is National Depression Screening Day – a reminder of all the misconceptions that surround depression, despite its worldwide prevalence as a leading cause of disability.

While many people mistakenly view depression as a matter of willpower or weakness, it’s a complex illness that can affect anyone. If you live with major depressive disorder, unpacking its root causes is crucial for healing.

Beyond the Blues

Depression is a potentially severe medical condition that can impact your mood, energy levels, concentration and even physical health. Some people experience major depressive episodes only once, while others live with persistent or recurring symptoms that interfere with daily life.

  • Constant sadness or emptiness
  • Loss of interest in previously enjoyable activities
  • Changes in sleep or appetite
  • Fatigue or lack of motivation
  • Feelings of guilt or worthlessness
  • Difficulty concentrating
  • Thoughts of death or suicide

Depression can affect anyone, regardless of their beliefs, socioeconomic status, gender identity, age and ethnic heritage. While there’s no single cause, various contributors could increase your vulnerability.

Biological and Genetic Factors

If a close family member has experienced depression or another mental illness, you may be more likely to develop a similar illness. However, genetics alone do not determine your fate. Environmental influences and personal experiences also shape how your brain and body respond to stress. Imbalances in neurotransmitters such as serotonin, dopamine and norepinephrine can also affect mood regulation, which may make you more vulnerable to developing depression.

Environmental and Life Events

Traumatic or stressful experiences are well-known depression triggers. Examples include:

  • Childhood neglect or abuse
  • Relationship conflicts or divorce
  • Financial instability or job loss
  • Chronic illness or pain
  • The death of a loved one
  • Life transitions, even positive ones

Over time, repeated exposure to stress can alter your brain chemistry and make it harder to bounce back emotionally. When left unaddressed, these emotional burdens can evolve into major depressive disorder or co-occurring mental health conditions like anxiety or substance use disorder.

Co-Occurring Mental and Behavioral Health Disorders

Some people self-medicate to numb their sadness or escape painful emotions. Unfortunately, substance use tends to worsen depression over time, creating a cycle of dependency and despair.

This overlap is a dual diagnosis – when someone experiences a mental health disorder and a substance use disorder at the same time. Dual diagnoses require specialized, integrated care to address both issues simultaneously.

Why You Should Seek Help

Many people suffer with depression in silence, believing they can push through on their own. However, this mindset will only allow your symptoms to become more severe.
