I can't pretend to know what it feels like to be any of what LGTBQ stands for, so I welcome insights on this topic from those who do.
We as a society are going through some significant changes in how variations in sexuality and sexual identity are viewed and treated. While there seems to be greater acceptance of non-heterosexual lifestyles, there is still much animosity and I think fear from some groups of people who feel their religious beliefs are violated, or who worry that their children will be improperly influenced. In these ways, in some areas, it is probably particularly difficult to thrive if you are LGTBQ and it would be easy to feel marginalized or even fearful of being "outed."
Social problems such as suicide and unemployment run high in some communities. Prejudice and stigma have a large impact. Depression and anxiety can run high in the process of discovering where one falls in these categories and establishing supportive connections. Suicide rates are high among these groups, particularly where there has been rejection of important persons, such as parents.
