The fear of OCD is not false, but the compulsion to really be afraid is repeatedly suspecting, repeatedly worrying, repeatedly anxious, repeatedly afraid, which is most important in the repetitiveness, not its falsity. If you are afraid that you will jump if you stand on a high place, or that you will hurt yourself with a knife, you may also be afraid that someone is always going to target you, that you have some kind of disease, so you repeatedly suspect that you already have a disease, and repeatedly go to the hospital for consultation and examination, etc. These fears themselves have certain reasons and justifications, and the emotion of fear is also certain to exist. It is because of the great fear and anxiety, and at the same time the fear has some justification, that they make themselves think exhaustively and repeatedly, and this problem must be actively treated.
