There is a famous Sanskrit proverb which specifies the five things that can lead to serious nervous breakdown (depression or anxiety). Try to avoid following:
[a] Unsettled debt
[b] A Bad service of government
[c] Disgrace of oneâ€™s people
[d] Separation from a loved one
[e] And a friend who runs away from you because you are poor
Trust me, these 5 things burns the body without fire.
