I Want to Move Out of My Parents House

my parents and i have the shittiest relationship ever and i knew as soon as my sister moved back in with us my parents wouldn't talk to me nearly half as much. and i was right. just a few minutes ago, my sister and i were in the living room and my mom came home and she went through the living and into her room then my sister left and my mom came back in and started talking about my grandma, then looked around and went oh and stopped talking altogether until my sister came back in. i just want to leave.
