How can one overcome extreme anxiety and fear in professional life and manage the problem of financial extravagance and the accompanying regret?

Anxiety and fear may stem from a distance from Allah the Almighty. To overcome them, you must draw closer to Allah, and frequently recite the supplication: "There is no god but You; glory be to You, indeed I was among the wrongdoers." You should also recite the Quran and ponder its meanings, for it is a healing and a mercy. Furthermore, you should recite the prophetic supplication for worry and sorrow: "O Allah, I am Your servant..." As for spending money lavishly, it is extravagance and prodigality, which are forbidden by Islamic law, for Allah the Almighty says: {And do not be extravagant. Indeed, He does not like the extravagant} and His saying: {Indeed, the extravagant are brothers of the devils}. So, repent to Allah and try to avoid spending money outside its legitimate channels.
