Can't breathe feeling??

okay so today we went to go get our school schedules. I was about to leave when I saw my crush and suddenly my heart stopped for a few and I felt like I couldn't breath. I ended up staying a little longer (I wonder y, lol) and after I got done talking to a teacher I turned around and saw him looking at me and I kept looking at him so there we were both looking at each other, kinda having a moment and then I got that feeling again. I liked him last year too but I never had that I can't breath feeling. he is one of my good friends last year he was my best guy friend I say guy Because he wasn't like a best best friend. I also found out that he is on my team this year so yes we will have classes together. but I don't get what has changed from last year to this year and why now I get that I have the can't breath feeling.
