How can I free myself from my difficult psychological state and social isolation, given the absence of family support, suffering from mental illnesses, and having a desire to die to escape this exhaustion?

We praise Allah for your diligence in acts of worship despite the difficult circumstances. Worldly certificates are not a true measure of success or failure, for whoever reaches Allah is truly successful, even if deprived of worldly delights. The proof of this is the noble Hadith: "The most privileged person in the world from the people of Hellfire will be brought on the Day of Resurrection and dipped once in the Fire... And the most miserable person in the world from the people of Paradise will be brought and dipped once in Paradise..." To compensate for the shortcomings in your education and care, we recommend the following: continuous supplication to Allah and obedience to Him, attending circles of knowledge or following religious lectures, communicating with psychologists for cognitive-behavioral therapy, using Prozac 20 mg daily in the morning for a month and a half (while noting its side effects and consulting a doctor), engaging in sports, household activities, and charitable deeds, and utilizing educational websites on the internet.
