Does anyone feel like they’re on drugs when they have a crush ?

I saw this guy once and I feel so much happier like ABNORMALLY happy. And he’s not responding which is frustrating me so much. I barely know him we saw each other for one hour but I feel in love with him and I feel so much happier than two days ago , like I feel on top of the world . I haven’t had a date in so long so this makes doesn’t help. Is this a bpd thing ?? I feel so happy I can’t even think of anything except him, it feels like I’m on drugs and it will fall apart as soon as he’ll leave me . I just want to know how other people deà with this
