I know how it feels too. This boy in Elementary School used to bully me!! And you shouldn't hate your life because there is always good things that you have in life! And one day you will find real friends because there are people out there who don't even have any!!
Here's some advice:
If they talk about you let them talk about you and ignore them, but when they bring up your family then that's when you open your mouth and say something!! Good luc hope you'll feel better!
