What Is Depression?

Many often describe and say that depression is just a feeling of being sad or a state of extreme sadness. But If that were the case, then every single person in this world has dealt with depression.

Everyone has gone through phases of experiencing sadness in their lives. The ending of a relationship, the loss of a cherished one, or losing a job are all difficult experiences for a person to endure but it is very normal. The intensity of this sadness is what often leads to depression.

Depression is a different form of sadness/grief or bereavement. For example in grief, one can experience waves of sadness intertwined with positive thoughts of the deceased.

The mood or interests of the person experiencing grief are decreased for more than two weeks, but for a person experiencing depression it continues for more than those two weeks.

The self-esteem of the person experiencing grief is usually maintained but in depression, the feelings of worthlessness and self-loathing are experienced.

It is hard to trace the roots of depression because different circumstances/experiences can cause it. For some people, it can be the death of a loved one, having a traumatic childhood/experience, or even losing a job.

Distinguishing the source of your feelings is an important deciding factor in establishing whether you have depression or not. That is why it’s important to visit a specialist so that you can be able to get the support or treatment you need.

What Are The Signs and Symptoms of Depression?

Symptoms of depression can vary from mild to severe. These include:

  • Disturbed sleep

The Different Types of Depression

There are various types of depression disorders. Certain events in our life can cause some while chemical changes in our brain can cause others.

Symptoms can vary from minor to chronic, so it’s very crucial to know these types of disorders and their symptoms for you to seek professional help.

Some of these disorders have similar symptoms. It’s not a wise choice to self-diagnose yourself.

1. Psychotic Depression

People with Depression can lose a sense of reality and experience what we call psychosis.

Psychosis is a subtype of major depression that involves one experiencing hallucinations (hearing or seeing things that aren’t there) and delusions(having false beliefs that aren’t true).

The hallucinations can present itself in many ways but hearing voices is a commonality. Delusions happen when one believes that they are some kind of savior meant to save the world, etc.

One can also be in a state of paranoia feeling as though everyone is against them/wants to harm them or fearing that something bad is going to happen to them at any moment. Psychotic depression affects approximately one out of every four people admitted to the hospital for depression.

Common symptoms that are present in patients who have psychotic depression are:

  • Insomnia
  • Anxiety
  • Intellectual Impairment
  • Constipation
  • Agitation
  • Hypochondria
  • Physical immobility
  • Delusions or hallucinations

2. Major Depression

Major depression also is known as clinical depression/major depressive disorder or simply ‘depression’, usually involves one experiencing low moods or loss of interest/pleasure in activities that were once enjoyed. More symptoms are also present.

The symptoms are experienced most days and can last for at least two weeks or more.

In some cases, major depression has very little to do with your environment, You can have financial success, a loving family, amazing friends, and still struggle with depression.

Symptoms of this severe form of depression are:

  • Feelings of worthlessness or hopelessness

Major depression can ruin your life and relationships in general. These symptoms can last weeks or even go on for months. Some may experience a single episode of major depression while others can experience it throughout their lives.

3. Bipolar Disorder (Manic Depression)

Bipolar disorder also known as manic depression is a mood disorder.

It is called manic depression because the person experiences periods of depression and periods of mania – where one feels very happy with periods of normal moodS in between. Manic depression is an outdated name for bipolar disorder.

Mania/ hypomania is the polar opposite of depression. Symptoms of mania include a state of:

– Having lots of energy

-Feeling great

-Talking quickly

-Having racing thoughts


-Lack of concentration on basic tasks

-Feelings of frustration, and irritability.

Sometimes the person even loses touch with reality and can experience an episode of psychosis.

Depressive episodes have the same symptoms as major depression. These include:

  • Feelings of sadness or emptiness
  • Lack of energy
  • Fatigue
  • Sleep problems
  • Trouble concentrating
  • Decreased activity
  • Loss of interest in formerly enjoyable activities
  • Suicidal thoughts

The signs  of a manic episode include:

  • High energy
  • Reduced sleep
  • Irritability
  • Racing thoughts and speech
  • Grandiose thinking
  • Increased self-esteem and confidence
  • Unusual, risky, and self-destructive behavior
  • Feeling elated, “high,” or euphoric

Bipolar disorder can be triggered by stressful events and even conflict. It’s very common for bipolar disorder to be misdiagnosed as depression, schizophrenia, or (ADHD).

People can even go for years before receiving an accurate diagnosis of this disorder. This is why it is important to tell your doctor if you ever experiencing highs and lows.

4. Seasonal Affective Disorder

SAD (seasonal affective disorder) is a mood disorder that has a seasonal pattern. It is a kind of major depressive disorder that’s related to certain seasons.

The cause of this disorder has not been proved but it is characterized by having mood disturbances (experiencing periods of depression or mania) that start and end in a particular season.

With SAD, depression starts in winter and begins to subside when the season ends. A diagnosis is established after the person has had the same symptoms during winter for a couple of years.

People who suffer from SAD depression are more probable to experience weight gain, oversleeping, lack of energy, and even develop a craving for carbohydrates.

As the season progresses, seasonal depression can get worse and may even lead to suicidal thoughts but once spring begins to set in, symptoms tend to improve.

5. Situational depression

Situational depression has a lot of similarities to major depression. It occurs but when certain events or situations occur in one’s life. The events can be:

  1. The loss of a loved one
  2. Facing unemployment or financial struggles
  3. Being in a physically or emotionally abusive relationship
  4. Having been diagnosed with a terminal/serious illness

It’s completely normal to feel sad, angry, and even worthless when events like these happen but situational depression happens when these feelings are prolonged and begin to affect your daily life.

Situational depression symptoms normally start within three months of the initial event and can include:

  • Changes in appetite
  • Sadness and hopelessness
  • Frequent crying
  • Trouble sleeping fatigue
  • Social withdrawal
  • Muscle aches and pains
  • Anxiety
  • Lack of focus

6. Persistent depression

A persistent depressive disorder is a kind of depression that lasts for two years or more. And is also known as chronic depression or dysthymia. Persistent depression may not be as dangerous as major depression can still affect one’s life and relationships.

Even though it’s not a long-term form of depression, the severity of the symptoms tends to decline for months at a time before arising again.

Some people can have episodes of major depression before or while they have a persistent depressive disorder. This state is known as double depression.

Symptoms of persistent depression include:

  • Concentration and memory problems
  • Difficulty functioning at school or work
  • Inability to feel joy, even at happy occasions
  • Social withdrawal
  • Deep sadness or hopelessness
  • Low self-esteem or feelings of inadequacy
  • Lack of interest in things you once enjoyed
  • Appetite changes
  • Changes to sleep patterns or low energy

Persistent depression can last for years at a time, so people with this condition can start to feel like their symptoms are just a part of their normalcy

7. Atypical depression

Atypical depression is depression that temporarily goes away upon the response to implementing positive changes. Despite its complex name, atypical depression isn’t rare or uncommon. 

Having atypical depression is very challenging because one may not always look depressed. It can present itself during an episode of major depression, and can occur with persistent depression too.

Why Depression Is Hard to Diagnose

According to certain studies, 50-70% of patients with depression in primary care remain undetected, with somatization being one of the most important factors in misdiagnosis.

Somatization is derived from the word somatic symptom disorder.

A somatic indication is when a person has a significant focus on physical symptoms such as pain or weakness, that results in inducing major stress and problems with functioning. The person has excessive thoughts, feelings, and behaviors relating to physical symptoms.

This is why it’s important for your doctor shouldn’t focus on somatic symptoms but rather your emotional health by asking you questions concerning possible events that may have occurred preceding the symptoms.

If you think you are experiencing depression of any form seek a psychiatrist or a mental health professional immediately. Depression is treatable given the right treatment. Give your doctor as much information as possible.
