How can one return to the truth and overcome weakness of faith, negligence in worship, and being drawn towards forbidden things, and is the weakness and distraction one experiences a sign of Allah's wrath?

You are in great danger by abandoning prayer and committing sins. Therefore, you must have an honest self-assessment to reorganize your affairs. Wake up from your heedlessness, strive against yourself to perform acts of obedience, and abandon sins immediately. Strive in your studies to achieve success. Change is in your hands, so be determined, diligent, and sincere, and Allah will guide you to His ways, in accordance with His saying: "And those who strive for Us - We will surely guide them to Our ways. And indeed, Allah is with the doers of good." (Al-Ankabut: 69).

What will help you in your struggle: 1. Reflecting on Allah's names and attributes, and being mindful of His knowledge of you and His fear. 2. Accompanying the righteous who will assist you in matters of your religion and your worldly life, and avoiding the companionship of those who push you towards abominations. 3. Increasing supplication and humility to Allah, for He is the turner of hearts.
