I came out as a teenager and I regret it now that I'm older
I was one of those people who knew she was gay from literally elementary school. My first crushes were never on boys, only girls. I came out as a teenager and I really regret that now that I'm an adult.
Coming out really sucked and made my parents cry. Since then, they've casually outed me to a bunch of people because they don't understand how personal it is. Many people treat me differently now that they know. Now that I'm working in education, I worry that a parent will eventually hear about it and have issue with it. It ended up not mattering because I never ended up finding someone anyway. So I basically created these problems for myself for no reason.
I spent some time living abroad and never told a soul there. I basically got an opportunity to have an experiment of what my life would have been like if I never came out. It was so much easier. I never worried about parents of students finding out because nobody in the whole country knew or had contacts to anyone I knew in my home country. I never had friends suspicious that I was "secretly into them." I wasn't paranoid that someone would think I'm a creep when I needed to use a changing room.
And now that I'm moving back to my home country, I really wish I had set up this same life for myself by never coming out. It's just so much easier.
