What is the solution for severe symptoms of obsessive-compulsive disorder (waswas) that include continuous discharge of urine and prostatic fluid (madhy) during ablution (istinja'), feeling aroused, and the intentional or involuntary discharge of urine drops and gas (farts) during ablution (wudu') and prayer, leading to spending long hours in the bathroom and repeatedly performing ablution?

Completely ignore the whisperings (waswas). When relieving yourself, cleanse quickly by pouring water over the area of impurity, then stand up, and pay no attention to the illusions of urine exiting.

If it is determined that urine has exited, place a cloth over the area to prevent the impurity from spreading, perform ablution (wudu), and pray. What has exited will not harm you; your ruling is that of one afflicted with urinary incontinence (sahib al-salas). Perform ablution after the time for prayer begins, and do not repeat ablution or prayer. By ignoring the whisperings, the hardship will be removed, Allah willing.
