My mom said harsh things?

my mom said very harsh things to me last night. i'm trying to get all the help i need in math and things are still not working. i failed a quiz and a midterm. she was like you gotta start acting like your age im 23 i do act it she was like your just gonna cry. i couldn't help crying hysterically.it she even said i'm tired of taking care of you and even said she may or may not come home today. i want to stay in school and graduate.i went for extra help as much as i could. it's a hard cl. i want to speak to a counselor but she's not gonna pay anymore. shall i speak to my friends and my boyfriend when i say i dont want to talk about it anymore tonight she thinks im running away but it means i've had enough of fighting for tonight. she doesn't even trust me. my mom can be harsh. i wish i could move in with my boyfriend or a friend. i need help.
