This research aims at understanding the high suicidal risk of the young lesbians and gays. For that purpose, we evaluated potentials connections between their suicidal risk and the important stress they felt during the coming out. Semi-directive interviews were realized with 15 young people considering thremselves lesbians or gays. Within our sample, three young people had made a suicide attempt, among which two in connection with their coming out. Our results demonstrate that this disclosure may generate important distress and lead some young people trying to take off their life, essentially when it rises negative attitudes. But it can also cause well-being and relief, primarily when it leads the young person to benefit a more important support.
