Help?

I’m not really sure what to call myself. I think I’m a part of the community, I’m pretty sure I’m bi. But I don’t want to come out as something I later realize was wrong and then contribute to the “it’s just a phase” saying. I feel like I’ve realized too late for me to be bi. I feel like everyone knows when they’re really young, but I’m 16 and just figuring stuff out. I feel like I’m not being my true self, but I also don’t know what my true self is
