What are the best ways to ignore obsessive-compulsive disorder (OCD) that has caused physical illnesses and prevented the reading of the Qur’an and prayer, after 14 years of suffering, and what should the questioner do about the fear that ignoring it will lead to feeling that forbidden things are real?

There is no cure for obsessive thoughts except to turn away from them and ignore them. They do not harm your faith; rather, your dislike of them is proof of the sincerity of your faith, and you will be rewarded for struggling against them. These obsessive thoughts are from the plots of Satan, so foil his attempt and resist them, and do not dwell on them. The more you ignore them, the lighter they will become until they vanish. You may consult a trusted doctor.
