Is a committed girl's following of a Korean male singing group, saving their pictures, listening to their songs, and watching their dances and shows—while knowing that music is forbidden—considered persistence in sin and continuation in disobedience that could lead to God's wrath and her perdition, and what is the way to get rid of that?

All praise is due to Allah, who has blessed you with wearing the hijab, observing prayers, and avoiding communication with young men. These are great blessings that deserve gratitude. Listening to music, admiring young men, looking at their pictures, and following their news is a dangerous matter and involves disobedience to Allah. Therefore, sincere repentance is due for all of that. If you falter, hasten to repent again and do not despair, for repentance is accepted even if the sin is repeated. Do not think that returning to these actions will remove depression and obsessive-compulsive disorder, for sins are a cause for the devil's dominance and the continuous succession of worries and sorrows. You have done well by supplicating and asking for steadfastness, so continue to do so.
