In Bukhari and Muslim it is narrated that the Messenger of Allah (May peace and blessings of Allah be upon him) used to say for GRIEF, STRESS, DEPRESSION, ANXIETY:
“There is no god but God, the Incomparably Great, the Clement; there is no god but God, the Lord of the mighty Throne; there is no god but God, the Lord of the heavens, the Lord of the earth, and the Lord of the noble Throne.”
The Prophet (May peace and blessings of Allah be upon him) said: Whenever a sadness, grief, or anxiety strikes a slave and the slave then says The following, Then Allah will remove his grief
O Allah, I am Your slave, and the son of Your male slave, and the son of your female slave. My forehead is in Your Hand (i.e. you have control over me). Your Judgment upon me is assured, and Your Decree concerning me is just. I ask You by every Name that You have named Yourself with, revealed in Your Book, taught any one of Your creation, or kept unto Yourself in the knowledge of the unseen that is with You, to make the Qur'an the spring of my heart, and the light of my chest, the banisher of my sadness, and the reliever of my distress.

O Allah, I seek refuge in you from grief and sadness, from weakness and from laziness, from miserliness and from cowardice, from being overcome by debt and overpowered by men (i.e. others).
