Visit an actual psychologist that you can talk to personally. (online psychologists like Peterson are not enough)

Or try to talk to your parents or other trustworthy members of your family.

People might not believe you and for all I know you might be a troll. However, I have personally been through similar obsessive phases in my life. In the past I almost committed suicide over an obsession. I guess some people are more vulnerable than others. You know what helped me? Finding some friends and getting closer with my family members. When you have close relationships with people it's harder for obsession to start influencing you imo. On the other hand, being alone is an anathema for people who suffer from obsessive behavior.
