What should I do when I feel distressed, despite my fear of God and my desire to follow His path?

Among the things that help maintain steadfastness in obedience and avoid instability in faith are: choosing righteous company that guides to good, establishing a daily program for reading books on spiritual refinement (Raqā’iq) and those that encourage good deeds (Targhīb) and warn against evil (Tarhīb), frequently contemplating the terrors of the Day of Judgment and the states of the people in their graves, always remembering death, and cautioning oneself against dying upon a path displeasing to Allah.
