My mother angers me, im not sure how much more I could take.

Title says it all. I (18M) live with my mother until I'm off to college around August. I used to be hesitant about saying I hated my mother, because I know she's broken and struggling, but i truly mean it. I tried seeing the good in her, I tried confronting her but she won't change. The one time I tried standing up for myself, she threatened to throw my niece's tablet at me. I just told her to do it, and that it won't change anything and eventually she'll just feel bad because that's what always happens whenever my mother would get physical with me. She didn't, thankfully, but she just told me to get out of her face. My mother is a bitter, miserable woman and nothing is gonna change that. She manipulates, she gaslights; she was arguing with my sister dismorning, and everything she said just made me roll my eyes. She can't see herself beyond a victim, and kept trying to provoke my sister when she wanted to be left alone. I despise her, and everything about her disgusts me.
