When I was younger, I had to keep my mouth shut to not out myself and cause drama while some family & the church had quite a bit of negative things to say about the lgbtq. I dealt with it by partly listening and partly dissociating (spacing out) when it got too stressful as a coping mechanism so I didn't have to hear it. But I didn’t do well enough I guess to keep my expression neutral once and ended up getting outed by a suspicious uncle during a church service...
In school, I was a piece of shit sometimes because I didn't want people to know I had some same gender attraction to others (which I’ve since apologized for and made up for.). I also had a lot of self-hatred for being bisexual that took years for me to accept.
