I cant stop thinking about this girl i just met?

like we barely said two words to each other but im so infatuated with her. and like i think she likes me too, ( im pretty sure ). shes so damn gorgeous.but thing is i only have like one day left before i leave the country, and i dont know how to get in touch with her other than she knows my friends. is it normal to b this way?? like i dont want to regret not doing anything later on.
