What is the way to get rid of self-distrust and the ability to possess it, which led to failing the baccalaureate?

A Muslim should be strong-willed, resolute, and seek help from Allah. Whoever strives finds, and whoever sows reaps. Failure in an exam is a motivation for diligence and striving. The Lawgiver has encouraged us to adopt means of strength. The Prophet, peace and blessings be upon him, said: "A strong believer is better and more beloved to Allah than a weak believer, and there is good in both. Be keen on what benefits you, seek help from Allah, and do not be helpless. If something befalls you, do not say: 'If only I had done such and such, then such and such would have happened,' but say: 'Allah has decreed, and what He willed He did.' For 'if only' opens the door to the work of Satan." Failure happens to many people, but they rise again and learn from their past experience.
