I'm unhinged's Things

I've seen many pretty girls in my 19 years of life and I'm very much sure I'm straight.I've dated a guy before but it lasted just 2 weeks or so since I got disinterested.I've never dated anyone after that since I considered it to be boring.
Getting to the point, there's this specific girl I very much like and it's the first time I've felt this way.I saw her some few times and now I can't stop thinking about her.I get nervous and my hands shake everytime she's near me.She stands out very much among the other girls,I always glance at her eveytime I get the chance admiring the way she walks and talks.Is it just admiration or more than that.I always find myself trying to meet each other by coincidence.
Idk I am so goddamn confused.
It also pains me that I still haven't talked to her and on top of it,I think that she's 100% She's 2 years older than me.
I have an unrequited crush of 4+ years for a boy too but I've 80% moved on from him.I just want tto know what you guys think about this.
