What is the solution to the problem of obsessive-compulsive disorder caused by excessive thinking and not getting a job, along with physical symptoms such as heart fatigue and colon issues, and fear of death and mental illness, especially since the patient denies his illness and refuses treatment?

It is recommended to mend the relationship with Allah Almighty through repentance and performing acts of worship, and by frequently remembering Allah and seeking refuge in Him from Satan. To treat obsessive thoughts, one must turn away from them and not respond to them, as stated in the Hadith: "Let him seek refuge in Allah and desist." It is advisable to visit a doctor and receive medicinal treatment along with behavioral therapy. One should also be content with Allah's decree and destiny regarding sustenance and work, for every soul will not die until it has received its full sustenance, alongside striving and diligently working. Remember that the affair of the believer is all good; if prosperity befalls him, he is grateful, and that is good for him; and if adversity befalls him, he is patient, and that is good for him.
