What is the way to overcome a recurring old sin and repent sincerely from it, along with providing evidence for the absence of jinn possession, and what should you do about the resentment of her family?

Here is the English translation of the provided Arabic text:

A piece of advice for a girl who feels deficient and guilty and is suffering from some problems: she is urged to make sincere repentance and to strive against her soul to abandon sins, seeking Allah’s help, and reminded of the seriousness of sins and Allah Almighty’s constant watch. She is advised to be regular in prayer because it forbids indecency and evil. As for her feeling that jinns are interfering, these are not delusions. Her relationship with her family should be dealt with kindly or by warding off their evil.
