Will the symptoms I feel, such as extreme fear, chest tightness, aversion to people and the world, and negative thoughts about the future, study, work, and marriage, continue indefinitely or do they have a specific duration?

We advise you to continue with ruqyah (definition) (Islamic exorcism) and divine treatments, and to consult specialists and psychiatrists.

Supplicate to Allah Almighty to remove this affliction from you, for supplication benefits against what has descended and what has not descended. Do not let what has befallen you lead you to abandon what benefits you, such as studying, earning a living, or marrying. Rather, continue to strive by all means to achieve what benefits you. Be keen on what benefits you, seek Allah's help, and do not despair. Increase your supplications and do not be hasty. And keep the company of the righteous.
