For me, the ability to talk aloud about stuff changed everything. I was able to discuss things which until then I'd only kept to myself. It gave me another perspective and helped me understand things and connect the dots.
Also, it feels really nice to be able to join in with friends when they talk about their personal lives. I couldn't for the longest time and finally being able to is amazing.
I haven't come out and because I don't feel a need to come out to everyone. I'm not really all that stereotypically "gay" irl so no one really suspects it. Only my closest friends know and coming out didn't change my relationship with them sooo.
