What is the interpretation of my friend's condition, as she suffers from sadness, loneliness, lack of self-confidence, negative thoughts, and thoughts of death, and how can she be helped to overcome her weakness and sadness?

The sister is suffering from psychological pain and illness, and she must turn to Allah Almighty, for Allah answers the distressed and removes evil. She should approach the Quran and reflect upon it, and have a good opinion of Allah. She must also rectify her relationship with Allah and not allow the bad treatment of others to justify her disobedience to her parents. She needs to break out of isolation and associate with good company. As for her severe attachment, it is advised to visit a trusted psychiatrist, and general advice is offered to alleviate this attachment, such as distributing love practically, associating with serious individuals, engaging in useful activities, supplicating, reciting the Quran deeply, and being warned against the dangers of attachment to others.
