How can I follow the straight path and escape Allah's punishment and wrath, while currently suffering from nervous exhaustion, obsessive thoughts, and a mental breakdown for which I am undergoing treatment?

Praise Allah for repentance, for it is better than the world and all that is in it. The path of repentance requires striving against the self to make it upright, and Allah is with those who do good. Persevere in repentance by supplicating to Allah to keep your heart steadfast in His religion, and by increasing in acts of obedience such as prayer, fasting, reciting the Quran, and giving charity. Accompany the righteous, for they are a blessing and a support, and avoid the people of deviation and misguidance, for their companionship is evil. Repel obsessive whispers by seeking refuge in Allah, sitting with people of faith, and reflecting on Allah's creations.
