TopIntroduction
Depression is a frequent kind of mental illness. More than 264 million individuals of all ages suffer from depression across the world. Depression is a primary cause of disability globally and contributes significantly to the global illness burden. Women are more likely than males to suffer from depression. Suicide can be caused by depression. Depression is distinct from normal mood swings and short-term emotional reactions to ordinary stresses. For mild and severe depression, there are effective psychological and pharmaceutical therapies.
A person’s grief might be exacerbated by the death of a loved one, the loss of a career, or the termination of a relationship. It's natural to experience melancholy or grief in reaction to such circumstances. Those who have suffered a loss may describe themselves as depressed.
However, sadness is not the same as depression. Grief is a normal and individual process that shares some of the same characteristics as depression. Grief and depression can both cause extreme sadness and a withdrawal from daily activities.
They're also distinct in a number of ways:
- •
In sorrow, painful emotions come in waves, frequently intermingled with happy recollections of the departed.
- •
Self-esteem is generally preserved during bereavement. Feelings of worthlessness and self-loathing are frequent in severe depression.
- •
When thinking about or daydreaming about joining a departed loved one, thoughts of death may arise. The goal of serious depression is to terminate one's life because one feels worthless or undeserving of live, or because one is unable to cope with the anguish of despair.
