I have a similar problem to yours. I am bisexual (in my case this means i am attracted in that way towards women and nonbinary people), omniromantic (i can feel romantic attraction towards all genders, but i prefer some genders over others) demiflexible (normally i have to know someone and have some kind of connection with them to fall for them, but occasionally i will just fall for people anyway) greysexual (if i feel, um, THAT kind of attraction i only feel it very weakly, or i feel it but i dont, you know, actually want to really be really close with anyone) and gynesexual (i am generally attracted towards women and feminine people). I also think I might be a demigirl.
I’m pretty sure that my mum supports the LGBTQ community, but my dad has made some transphobic and homophobic comments, so i dont know whether I should come out or not. My suggestion would be to tell your closest friends, but only if you really trust them. My current mission in life is to come out to everyone but my parents /jk XD
