unfortunately possibly lesbian

I have never really used reddit before but I'm turning to these communities as I'm too embarrassed to talk to my friends LOL

Im a teen, I don't really want to say what age but 14-17. I've never really felt any romantic attraction to anyone, I've found a few characters cute or hot and it's always been a mix but that doesn't really mean anything. I've always been teased to have a secret boyfriend and I live in a sort of anti LGBTQ family, mainly a family that "doesn't have issue with it" but would lose it if a family member was (if that makes any sense??)

anyway, Im starting to think I genuinely like my friend. I never thought about it before but sometimes we jokingly flirt and it makes me feel happy like I'm genuinely being called things like babe and stuff like that..I also caught my self being INCREDIBLY disappointed when she said she didn't like me because "oh yeah we arent gay haha!!" And it really fucked with me. Idrk how to feel about ANY of this..I mean?? I just physically cannot picture myself being a lesbian. I have NOTHING wrong with lgbtq at all it just feels wrong for me to say that I am. I don't really know what to do.

I think I genuinely like her but should I act upon it or just shove it all down and pretend it isn't there?? Ik afraid for both of those outcomes :((
