When is seeking forgiveness for a sin considered a mockery of religion, especially if the one seeking forgiveness persists in that sin, and is not being completely disciplined during work hours except when inspected considered polytheism (shirk)?

It should be noted that the questioner suffers from obsessive-compulsive disorder. He is advised to seek forgiveness from Allah (Istighfar) and to have sincere intention in seeking righteousness and divine assistance. His condition does not indicate mockery of Allah, but rather a weakness of self and a fall into sin. There is no major or minor shirk in adhering to work appointments to escape problems, although this should be done with a good intention to be mindful of Allah, fulfill trusts, and perform duties. The most important thing is to commit oneself to that which benefits both one's religious and worldly affairs, and this includes adhering to work appointments and performing them diligently.
