Bullied by a classmate bc i have a crush on a girl in my classroom

One of my classmate in a break started punching me. Then he started to say a different lies about me to embarrass me in the front of the class. then he started making jokes about me that I have a crush and you realise that it was embarrassing for me as well as the girl in my class that I had a crush on. half of the classroom started laughing at me and I got under a desk to feel a little bit protected.
