How can one overcome the intense fear of marriage, women, and failure, which has become a psychological barrier, despite the latent desire to marry and form a righteous family?

This tribulation is a test that requires you to have a good opinion of Allah, and patience and seeking reward, and to deal with obsessive-compulsive disorder, which is from Satan. Its treatment is as follows: reading Surat Al-Baqarah daily, maintaining remembrance of Allah (dhikr), increasing supplication (du'a) during times of answered prayer, seeking forgiveness (istighfar), exerting effort to repel the whispers (waswas) and not surrendering to them, proceeding with marriage and seeking help from family and friends, and consulting psychological specialists for supportive treatment.
