What is Depression?
Depression is more than sadness. It’s a whole-system experience — emotional, cognitive, physical, and relational — that alters how a person experiences themselves, other people, and the future.
Clinically, the condition most people mean is:
Major Depressive Disorder
It is a mood disorder characterized by persistent low mood or loss of interest/pleasure, lasting at least two weeks, along with other symptoms that impair functioning.
Core Emotional Symptoms
- Persistent sadness, heaviness, or emptiness
- Loss of interest or pleasure (anhedonia)
- Irritability (especially common in some women and adolescents)
- Tearfulness or emotional numbness
Cognitive Symptoms
- Harsh self-criticism, guilt, shame
- Hopelessness (“Nothing will change”)
- Difficulty concentrating or making decisions
- Negative filtering of reality
- Thoughts of death or suicide (in more severe cases)
Physical / Biological Symptoms
- Fatigue or low energy
- Sleep changes (too much or too little)
- Appetite or weight changes
- Slowed movement or agitation
- Decreased libido
Different Types of Depression
- Persistent Depressive Disorder – chronic, lower-grade depression lasting 2+ years
- Postpartum Depression – occurs after childbirth
- Seasonal Affective Disorder – linked to seasonal light changes
- Bipolar Disorder – includes depressive episodes alternating with mania or hypomania
What Depression Feels Like (Experientially)
Many people describe it as:
- “Moving through mud.”
- “Living under a heavy gray blanket.”
- “Being cut off from myself.”
- “Nothing matters.”
- “I’m a burden.”
It often shrinks the world. Choices feel overwhelming. The future looks flat.
Causes: It’s Multifactorial
Depression can involve:
- Genetic vulnerability
- Neurochemical shifts
- Trauma history
- Chronic stress
- Hormonal changes
- Medical conditions
- Learned cognitive patterns
- Suppressed anger or grief
- Social isolation
It’s rarely “just one thing.”
From a Depth / Parts Perspective
- Depression can sometimes function as a protective part that shuts down feeling to avoid overwhelm.
- It can represent anger turned inward.
- It can signal un-lived life, frozen grief, or blocked agency.
- It may be the psyche’s way of saying: “Something must change.”
In some clients, depression is collapse after years of over-functioning — especially high-achieving women who carry everyone else.
Important Distinction
Sadness is responsive and connected.
Depression is persistent and impairing.
Sadness says: “This hurts.”
Depression says: “Nothing matters.”
Treatment Options
- Psychotherapy (CBT, psychodynamic, EMDR, parts work, hypnotherapy)
- Medication (SSRIs, SNRIs, others when appropriate)
- Exercise and sleep regulation
- Light therapy (for seasonal patterns)
- Social reconnection
- Meaning-making work
Severe depression may require more intensive treatment.
