Gender Identity Crisis

I don't know how to properly say this, but I feel I need to say it. I don't feel like I belong in the he/him category. I've never truly felt like a "man" as my family growing up would say. Growing up and in my dreams I looked in the mirror and I've have longed my whole life to be a mother/woman.

I see myself as something I'm not and I feel trapped by my existence. I've been scared to admit it. I hide behind a non binary flag because I'm scared to step in any direction and I'm so uncertain on what to do and who will accept me
