I can accept every trans person except myself

Every time I start thinking about my gender identity, I believe it's a stupid thing and that I'm just a girl going through puberty who doesn't like gender stereotypes, and there's nothing to worry about. I love and accept all trans people and appreciate when people become who they want to be. But I'm scared of coming out as not cis. I'm afraid of what my family and the people I know will think of me in a bad way. I know I shouldn't care, but I do. Sometimes I think about adopting religion and just doing what girls usually do, but that's not the path I want. Every time, it just makes me feel bad
