my mother and little brother bully me

yes I said it... I have a weird relationship with my mother and would wanted to know if this is actually normal. I'm 18 years old and I have a boyfriend whom isn't fond of my family due to them talking shit about me, taunting me, and at points hitting me. However, when I have a situation of coming home late.. she tends to put my little brother who is 14 years old to have an opinion in which they both call me slut, loser, you are gonna get pregnant soon and you are dead to me. is this normal and should I pack my things? this have been going on for a long time
