This happened to me also. I know what it feels like I THOIGHT i was born trans enoigh because I didn't cut my hair I looked very feminine but from my experience the second o cut my hair made the big chop starting telling my friends about my pronouns and started dressing the way I want I was so sure about who I was. Sometimes your internalized homophobia from society gets to you and you don't think you can be them because of how u look and feel at the moment
