In school? Just marginalised can mean kids not wanting to be your friends, having difficulties forming groups for activities… All sorts of stuff that make your life harder. The word comes from the literal sense of being put to the margin, to the side, outside of the general circle.
It can easily devolve into being bullied aka made fun of for being different, kids using hurtful aliases to call you, hit you, abuse you…
Depends on where you live and all that but being singled out/marginalised can easily leave you in a position where bullies will pick on you and since you are alone, no one will defend you.
