What should a 19-year-old girl do who prays but feels that something is hindering her from prayer, lacks the desire to complete her university studies, wishes for death, and has even thought about suicide?

The sister and her family must strive to treat the illness by every legitimate means. The greatest cure is to turn to Allah sincerely, for He is the One capable of removing harm. Allah Almighty says: "Is not He who responds to the distressed one when he calls upon Him, and removes the evil, and makes you inheritors of the earth? Is there any god with Allah? Little do you remember!" She should also associate with righteous company. As for thinking of abandoning prayer or committing suicide, that is surrender to whispers (of Shaytan) and a loss of religion.
