Am I truly a believer or a hypocrite? Is my work purely for the sake of Allah or for show? What should I do about my current job, which requires interaction with the opposite gender (males), given my personal circumstances and my desire for religious commitment? How do I deal with my soul's weakness and my fear of people and hypocrisy? And how do I deal with Allah, with people, with my family, and with myself?
