Does the divorce of a man who insulted his mother and divorced his wife count, while he was unaware of what he was doing, especially with his female relative threatening him with an act that would make him intolerable to himself and those around him?

If you divorced your wife without awareness due to extreme anger, then your divorce is not valid, for the Prophet, peace and blessings be upon him, said: "There is no divorce and no emancipation in a state of closure [i.e., when one's mind is overwhelmed]." Anger is the key to evil, so you must be wary of it. Do not exaggerate in attributing problems to magic; rather, look at the apparent causes and address them with lawful means. If magic truly exists, its cure is easy through reliance on Allah and adherence to the prescribed remembrances and lawful ruqyah.
