What is the treatment for severe fear and panic regarding females and everything related to sex and marriage, which leads to isolation and avoidance of social occasions?

Severe fear of marriage and its physical symptoms is a pathological condition that requires consultation with a psychiatrist. The questioner has committed religious transgressions by attempting to establish relationships with girls outside the framework of marriage. Islam prohibits illicit relationships and everything that leads to them, such as impermissible seclusion (khalwa), uncontrolled mixing, and handshaking. It also commands lowering the gaze. Perhaps what he has been afflicted with is a punishment for him to repent.
