In the words of another Taylor, "never take advice from someone who's falling apart", so even if I had anything you probably shouldn't listen to me lol. I'm in a similar situation, it took me a lot longer to figure out my attraction patterns but I'm definitely bi, and only out online. I keep everything from my family, and I've lost touch with all my friends over the last few years, considering how homophobic they all were when I hung out with them regularly I don't think I'll ever come out to them directly either. I live in a religious dictatorship, so every school I've been to was some degree of religious, which has done more damage than I can ever fully mal out. I've never had the guts to ask anyone out, of any gender, so I understand that it must've felt like quite the landmark, even if your feelings weren't reciprocated this time. I guess all I can say is better luck next time, and stay safe.
As I said, I don't have any advice but I can point you towards the LGBTQ+ Group Support Chat here on cups, it's not the best place but I used to hang out there all the time before some of the regulars I was friends with stopped showing up. It's a ghost town most of the time, but when it's active it's one of the only places on this site where you won't be judged for your sexuality, and have a chance of starting a conversion with people who might have relevant experiences.
