<human>: Basically, I'm sick of living under my mother's rule. I love my house and the ease of living at home but she's narcissistic and I'm at my wit's end. 

My plan is that I'll move out in the next 8 months, as soon as I save enough money for a bond. I know I can afford rent if I work enough shifts, and I won't have a problem finding a place to live.

My problem is that I don't think Mum will let me. She's very passive aggressive and constantly berates me for not being independent enough, but if I told her my plans to move out she'd cry about how I'm abandoning her. 

How do I move out without her holding me back? She bought (offered) to buy almost all of the furniture in my room and I'm worried that she won't let me take any of it. How do I explain to her that I'm not abandoning her or cutting her out of my life?

Can you condense the text into three sentences or less?
<bot>: I'm worried that my narcissistic mum won't let me/will make it very difficult for me to move out. How do I deal with this?
