Ustadh, my friend has anxiety , stress a lot. He once raised his voice at his father, regrets it, and is working to improve. However, his sister still curses and mocks him, saying, “You ruined my life,” to justify her behavior, despite their father forgiving him. What should he do Islamically?

Ustadh AbdulAziz al-Haqqan
He should seek out medical help since he has psychological problems.
