I wish I was supported

I'm a bisexual when I was a kid I never realized how I would fancy over girls I saw on TV when I was 9 to 10 I became friends with this girl in girls girlscotts I always found her beautiful I always used to think about her I used to always wanna be close to her but now that everyone that I know knows that I don't only like guys they treat me like *** my dad calls me and *** and that he doesn't want a *** like me in his house and my grandma says that it's a phase I force myself to not like any girl cuz if I end up with one I know that I would have to hide it from my family
