What is the ruling on migrating from this world due to tribal vengeance that causes psychological distress?

The true believer does not despair, for despair is a characteristic of the misguided and the disbelievers. Suicide is not a solution; rather, it is a path to eternal misery. The believer combines good thoughts of Allah, sincere reliance upon Him, patience, and gratitude, thereby attaining good in every situation. And whoever fears Allah and is patient will find a way out and ease in their affairs, and they will have a good reward in the Hereafter. For Allah tests those whom He loves to raise their status.
