St. Oscar Romero (1917-1980 El Salvador) struggled with scrupulosity his whole life, but when he was 49 a psychiatrist diagnosed him with obsessive-compulsive disorder.
Already a priest, Romero had the humility to undergo psychoanalysis and seek counseling at a time when mental illness was spoken of only in hushed voices.
He continued to deal with his OCD throughout his life, including during his work as archbishop fighting for the rights of the oppressed, for which he was ultimately killed.
