I’m having an identity crisis

I feel like im being so annoying in class cause im being loud and obnoxious, my crush is most of my classes and i feel like she’s getting icked out or weirded out or smth like she doesnt show it but id probably be icked out. I think im trying too hard or smth i kinda miss how quiet (kind of) i was last year in 8th, but i didnt go super far being quiet but it worked wonders bc i met some pretty cool people but i dont like being quiet that much anymore- i have no problem with it but i like talking to people but i feel like im trying to be someone im not when im not quiet
