Running Away/Moving Out

I don’t want to get into what happened but I don’t currently have a very good relationship with my parents anymore. I can’t continue living with them so I decided I would live with live with either my aunt or my best friend. I need help because I don’t know how I should go about asking them and how I should tell my parents I’ll be gone without blatantly saying I’m moving out. The other problem is that if one of them agrees to let me stay with them for a while, I start school in a month and neither my aunt or my best friend live close enough to get me there every morning. Please help I really can’t stay with my parents any longer.
