How can one deal with the loss of passion and the academic and psychological deterioration resulting from mistreatment by a professor, and its impact on personal life, academic life, and acts of worship?

We advise seeking Allah Almighty's help and relying on Him, not succumbing to the devil's discouragement and laziness, and being diligent in organizing time and tasks. The first thing that must be given attention is prayer, for it is the pillar of Islam and the key to all good, as Allah Almighty says: ﴿And seek help through patience and prayer. And indeed, it is difficult except for the humbly submissive [to Allah]﴾. Prayer is sought for help in every matter; it is the scale of faith and forbids indecency and evil.
