Causes of depression
For depression to occur, there usually must be a reason. You were fired from your job, or you broke up with a loved one with whom you had a long-term relationship, or the death of a loved one.
Of course, it is natural in the current situations to feel depressed and, most likely, this condition is better called melancholy.
After some time, the depressed state should pass, because this is your life, and in life something happens all the time, and not only bad, but also good events.
It's worse when your depressed state becomes chronic. The feeling of depression becomes very pronounced; you cannot restrain your emotions, and even more so you cannot understand the cause of depression.
In this case, depression is accompanied by feelings of guilt, hopelessness, and emptiness. They may have thoughts about the futility of life, you in it, and even suicide.
