So a little backstory, my father [50s] died when I was 6 and my brother [21] died 2 months ago, also my mother is blind. So basically there's only me and my mother left.

Me and my "friends" like to banter a lot, myself included, but never so far

So basically I picked up some bread on the way home from school with 3 friends, they asked if they could have some ,and I said something like "Nah it's for the family", then they said stuff like "What family" "I bet you put 4 plates for dinner but then take them away" or "when you ask your mother for your family she says she hasn't seen them" during a minute or two, and all while laughing( hard to translate the jokes into English, but you get the idea ) So yeah they mocked my dead family members and made fun of my mother's disability

Needless to say I'm pretty fucking pissed, and also extra pissed because a close friend of mine was amongst the 3, they tried to apologize like rats but I told them to fuck right off. 

I'm wondering if i'm overreacting. And what I should do. Would appreciate an outside view from adults and such, thanks. Also, excuse any english errors as it isn't my first language
