The issue of suicide deserves its own page.  Suicide is so final.  Once a person is dead, he or she will always be dead. There is no coming back. An attempted suicide is probably the most dramatic, and most drastic, call for help a person can make. Sadly, many gay, lesbian and bisexual persons attempt or succeed at suicide. 

From: Sell RL, and Becker JB (2001). Sexual orientation data collection and progress toward Healthy People 2010. American Journal of Public Health, 91(6): 876-82.

YRBSS [Youth Risk Behavior Survey Surveillance] data from the localities that measure sexual orientation show that whatever the dimension of sexual orientation measured (sexual orientation identity, sexual behavior, or sexual attraction), sexual minority youths have higher rates of suicide attempts, victimization in school violence, drug and alcohol abuse, early onset of sexual behavior, eating disorders, and teenage pregnancy that other youths. As surveys of adolescents in Connecticut, Wisconsin, Oregon, and Seattle have demonstrated, even a measure of sexual orientation as indirect as perceived homosexual sexual orientation elicits disturbing correlation with deleterious health outcomes." (p. 878) When adolescents are assumed to be homosexual by other adolescents, they are treated accordingly. These youth are harassed on the basis of "presumed homosexual orientation," and they are at the greatest risk for the more serious suicide behaviors.
