I don't know what to do

I don't know what to do about my mom. We didn't get along when I was younger. I don't hold a grudge but now I just don't really like her. Like, if we met on the street, I wouldn't want to be friends. She just kind of annoys me.

She kicked me out on and off since I was 16 and I moved out for a few years when I was 18. Now, a few years later I'm living with them again. I hate living here. I don't want to leave my room because literally the second I open the door, my mom is trying to talk to me. I can't leave my door open or she'll just stand in the door and talk about stuff that I don't care about. I can't walk to the kitchen or she'll follow me the whole way there and the whole way back to my room. It's overbearing and frustrating. I tried talking to her about it that I don't always want to talk but she doesn't get it. I tried telling her that sometimes I just want to relax without having full conversations every time I leave my room/my door open. And she follows me Everywhere. When I was younger, she was very bipolar, always angry, kicking me out, yelling at me, throwing things at me. And she has always been too strict (telling me I can't shave my legs at 15), too overbearing, too controlling, and just too much. Like, I don't need to know where she's going every second of the day but she just let me know her whole plan for the day. I don't tell her when I leave or when I'll be back so I don't know why she tells me. (I'm just venting, I'm polite to my mom)
