I know it took me a while after realizing I was gay to not have some weekly panic of “What if I’m not a Real Lesbian™???” Sometimes I’d think no one would believe me if I came out to them, or even that I wasn’t “allowed” to be gay.
I want LGBT folks to know that it’s 100% normal to struggle with those feelings. You can talk to other LGBT folks about those feelings and still have acceptance. And also I want you to know that the impostor syndrome doesn’t last forever; eventually you will feel comfortable with yourself.
