I Need Help

So, today it was national girlfriends day and I don't understand the gist of it so I was having a conversation with my friend and I was even talking about observing people to understand their behaviour patterns and make a character inspired by those things .. then my friend searched about national feet day just out of curiosity.. in the search there was a phrase 'i love my feet' and i thought of joking around with that phrase saying things like does this phrase imply to you? Is this a sign? /J (and in reference to the observing the behaviour of people) my friend replied " You would be the type of person I'd just awkwardly nod to if you were a classmate And go oh... Then walk Away To be alone" and then (in reference to the feet) i said i did not hear a no and continued... "I am holding back from calling you several words So stfu don't say that stupid shit Again I just wanted to see if it's real" and then i said "Sorry brother you have to be victim to my stupid talk" then they said "Yeah you're getting blocked"
What should I do?
Not talk to them for a week?
Let them cool down?
Apologies again?

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.
