Just got bullied, and I'm 25

I'm not feeling well at all and I don't know what to do. I just got bullied in my dorm. A group of undergrads followed me into the elevator. Because of the weight limit, the elevator wouldn't go. One of them said, in Italian (assuming I wouldn't understand), that I had to get out. It was clearly an internal joke at my expense. I responded that I was first in line and shouldn't be the one to leave. I then heard them whispering and laughing. A taller guy then mocked me with some nonsensical words (I think he didn't know English). That's when I realized how messed up the situation was. It really shook me. I'm a foreign student here in Italy, and this whole experience has made me feel awful. Is this how I should expect to be treated just because I'm not white?
