Talk please

I just realized I’m pansexual i always new I liked girls and boys but there’s this boy In my class I like him very much and he’s trans I also like this girl in my class she’s also trans I like her to but I have a problem is I don’t know how to come out I live in a really cathlic family and I live with my nana and papa and my step mom doesn’t like LGBTQ+ and I think my dad will be cool with it I also have bipolar depression I have issues with my past and I have harmed myself but I’ve told my close friends about me being pan and they support me especially my friend that’s a boy he’s gay
