What is the treatment for depression and obsessive-compulsive thoughts that afflicted a young married woman after childbirth?

Obsessive-compulsive disorder (OCD) is an evil and an affliction often caused by the dominance of Satan. Therefore, you must seek refuge with Allah from the accursed Satan and increase your remembrance of Allah, because a Muslim cannot protect himself from Satan except by remembering Allah. You must also strive to turn away from these whispers and perform ruqyah (exorcism) upon yourself with the lawful ruqyah. It may also be beneficial to consult specialized doctors in psychological counseling.
