Why Does Depression Come and Go?

Depression is a serious yet common mental illness that affects millions of people worldwide. It can be difficult to understand and diagnose because symptoms vary from person to person and may come and go. For some, depression can be mild and come and go or last for a few weeks at a time. For others, it may be chronic and lead to more severe symptoms such as thoughts of suicide.

What are some different types of depression?

There are several types of depression, but some of the most common are major depression, bipolar disorder (manic depression), and seasonal affective disorder. Other types of depression include depressive psychosis, atypical depression, and situational depression.

Despite the type of depression or how long it persists, some of the most common symptoms seen across all types include:

  • feelings of sadness, worry, and anxiety
  • feelings of worthlessness and hopelessness
  • dark moods
  • lack of energy
  • sleep changes
  • appetite changes
  • unexplained aches and pains
  • trouble concentrating, making decisions, and remembering things
  • loss of interest in once enjoyed activities
  • difficulty getting through daily tasks
  • withdrawal from friends or family
  • thoughts of self-harm, death, or suicide

Major Depression

The main symptom of major depression is a feeling of sadness or emptiness that lasts most of the day, every day.

The symptoms of major depression, including feelings of sadness, gloom, or grief, can last weeks or months.

Some experience major depression throughout their life, while others may have a single depressive episode. Although, no matter how long some of these symptoms last for a person, they can still cause significant problems in one’s daily life.

Bipolar Disorder

Bipolar disorder is characterized by mood changes from feeling sad and down to feeling high and manic.

Someone must experience a manic episode lasting at least one week to diagnose bipolar disorder.

A few manic phase symptoms include:

  • racing or grandiose thoughts
  • increased energy
  • reduced sleep
  • uncharacteristic self-destructive behavior
  • feeling elated or euphoric

Persistent Depression (PD)

As the name suggests, PD is a type of depression that persists for most of the day, every day for two years or more.

While PD symptoms may not always feel as profound as major depression, they can still interfere with daily life and relationships.

Other symptoms include:

  • deep sadness
  • inability to feel joy, even on happy occasions

Seasonal Affective Disorder (SAD)

Seasonal affective disorder is characterized by a change in mood that coincides with a particular season. Most people experience symptoms of depression during the winter months due to shorter days and less sunlight, but they can also occur during other seasons.

Other symptoms include:

  • increased need for sleep
  • feelings of unworthiness

Depressive Psychosis

Depressive psychosis is marked by a change in mood accompanied by psychosis, which is a loss of contact with reality. Depressive psychosis can involve hallucinations and delusions.

Atypical Depression

Atypical depression is not unusual or rare, as its name suggests. Rather, it refers to depression that goes away temporarily when positive events occur in one’s life.

In some cases, a medical professional might also refer to atypical depression as a major depressive disorder with atypical features, as it is no less serious than other depression types.

Atypical depression can be tricky to identify because you may not always seem depressed to yourself or others.

Other symptoms include:

  • disordered eating; increased appetite and weight gain
  • poor body image
  • insomnia or sleeping much more than usual
  • heaviness in arms or legs throughout the day
  • feelings of rejection
  • sensitivity to criticism

Situational depression

The main symptom of situational depression is that it does not last for an extended period. Symptoms are generally triggered by a certain event, such as losing a loved one, developing a serious illness, or getting laid off from work.

While major depression develops and has little to do with what’s occurring in your life, the symptoms of situational depression typically start within three months of the initial event. Also, frequent crying is one symptom often seen with situational depression.

Still, situational depression is like major depression in several ways in terms of the symptoms themselves. With situational depression, one’s feelings start to feel out of proportion to what happened, which is similar to how there are no obvious reasons why one develops major depression.

Premenstrual dysphoric disorder (PMDD), a severe form of premenstrual syndrome (PMS), and perinatal depression are also severe types of depression but occur at specific periods in a woman’s life. If you struggle with severe symptoms of PMS, are pregnant, or have given birth in the past four weeks, talk to your doctor about managing these symptoms.
