Pathetic mother threatens to kick me out unless I respect her, even tho she doesn't respect me or treat me well!

Today I (20m) overheard a conversation with my terrible mother talking with my dad who's out of town and told her about what happened when we both went to the hospital. I already made a post about it. However, she told it from her perspective, and is mad that I wasn't on her side, and just overreacted about what happened. She even said that if I won't be on her side (which I won't given how she treated me and my family over the years) that she'll throw me out on the street! I never do anything to upset she, she always gets mad at liter everything, even the way we talk to her she immediately yells at us for the way we responded to her, even tho we're talking to her badly. Even if that bitch does kick me out, I have no where to go. I don't even have a job yet because I'm still working on my resume and I'm planning to start college soon. But I can't do anything with that bitch breathing down my neck. She already took away my phone for the mil time even tho I didn't do anything to her, she just overreacts and act like she's a victim, pathetic bitch. Even my sister is on her side and support her, even tho she treats her even worse than me, it's like she had the Stockholm syndrome or something? I honestly don't know how to move from this point, I have no friends I can reach out to. I already sick and tired of that women. I'm her son and she doesn't care about me!
