Is it okay for my mother to be treating me this way?

i’m 19 years old, i still live with my mom and im not in post secondary yet as i’ve been working the last year to save up for cosmetology school so that i can become a hairstylist. I was told less than 2 weeks ago that i’d be losing my job because i work at The Body Shop and the whole company has gone bankrupt, forcing us to shut down. i literally payed my mom $400 of my own hard earned money this morning because i pay her every month to live here at home. i also buy my own groceries and take care of myself. she looked me dead in the eyes and said “you better get another job right away because you’re an adult and you can’t live with me for free.” i literally told her that it could take some time and straight up she had the audacity to tell me that im “self entitled” and that im “manipulating” her? wtf? how?
also i’m her daughter, it’s not my job to take care of her. i want to move out and go to school but can’t fucking do that when half my money is going to her. i shouldn’t be helping her out, i don’t owe her anything.
