Depression is a mental illness that affects your mood, the way you understand yourself, and the way you understand and relate to things around you. It can also go by different names, such as clinical depression, major depressive disorder, or major depression. Depression can come up for no reason, and it lasts for a long time.

It’s much more than sadness or low mood. People who experience depression may feel worthless or hopeless. They may feel unreasonable guilty. Some people may experience it in form of excessive  anger or irritability. It may be hard to concentrate or make decisions. Most people lose interest in things that they used to enjoy and may isolate themselves from others. There are also physical signs , such as problems with sleep, appetite, and energy. Some may experience difficult thoughts about death or ending their life (suicide). it  lasts longer than two weeks, doesn’t usually go away on its own, and impacts your life. It’s a real illness, and it is very treatable. It’s important to seek help if you are unable to fight back.

It is a common mental disorder that presents with depressed mood, loss of interest or pleasure, decreased energy, feeling of guilt or low self-worth, disturbed sleep or appetite, and poor concentration. At its worst, suicide can also be possible.


The DSM 5  outlines the following criterion to make a diagnosis of depression. The individual must be experiencing five or more symptoms during the same 2 week period and at least one of the symptoms should be (1) depressed mood or (2) loss of interest or pleasure.     

  1. Depressed mood, most of the day, nearly every day
  2. Markedly diminished interest or pleasure in all, most of the day or every day
  3. Significant weight loss when not dieting or weight gain, or decrease or increase in appetite nearly every day
  4. A slowing down of thought or reduction in physical movements
  5. Fatigue or loss of energy nearly every day
  6. The feeling of worthlessness or excessive or inappropriate guilt nearly every day
  7. Diminishes ability to think or concentrate nearly every day
  8. Recurrent suicidal ideation without a specific plan or suicide attempts or a specific plan for committing suicide.


Here are some common causes of Depression:


Past physical, sexual, or emotional abuse can increase the vulnerability to clinical depression later in life.

Certain medications:

Some drugs, such as isotretinoin (used to treat acne), the antiviral drug interferon-alpha, and corticosteroids, can increase your risk of depression.


Someone who has the biological vulnerability to develop depression may result from personal conflicts or disputes with family members or friends.

Death or Loss:

The sudden death of any loved one can give a shock to an individual, it could create trauma. This can be lead to extreme sadness


Family history is another significant risk factor. You are prone to symptoms of major depressive disorder if your family has a background of any mood disorders. According to studies, depression is approximately 40 % determined by genetics.

Social environment:

Humans are social beings, they love to be around people, people`s opinions and acceptance mean an individual lot. It is one of the major determinants of mental well being. So social ignorance can also increase the risk of being depressed or low self-worth.

Past childhood experiences:

Experience of an individual`s life plays a very important role in mental wellbeing. Bad parenting, emotional abuse, bullying, ignorance and divorced parents, lack of support, dominancy and faulty beliefs, etc are the factors that can drive an individual to the rage of depression.


Thinking too much about some incident or any issue i.e, overthinking sometimes causes depression.


According to W.H.O , Health defines as the state of  complete physical, mental and social well being and not merely the absence of diseases or infirmity . And there is no health without mental health. Depression is the significant contributor towards the  global burden of diseases, it is estimated that 350 or more millions are suffering from major depressive disorders, in the average of 1 in 20 people reported have depressive episode, it become a serious discussion in present scenario. it is serious mental issue which can be happen to anyone .

Instead of ignoring  with name of sadness, we just to be attentive towards its symptoms such as depressed mood , loss of interest in pleasurable activities, decreased energy , fatigue and poor concentration etc.  Many times, it is invisible with hidden warning signs and sometimes it is slightly visible in the form of low mood or isolation , anger etc . But we need to be aware about it so that we can fight back more courageously.

“I can’t eat and I can’t sleep. I’m not doing well in terms of being a functional human, you know?”
