How do i end my last session with a bad psychologist?

I had a horrible session with my psychologist. She was judgemental, negative and rude. She said things like "..you won't tell your therapist your uncle's name?", "a 16 year old knows to get a job to gain independence" "most people get a job, any job" She gave me too much of her negative opinion and bad attitude. She didn't listen to the concern I started talking about and psychoyzed me without knowing much about me. I felt like i was defending my spirit and soul against a negative force that I'm supposed to feel safe with. It messed me up for a couple days and felt horrible about myself. She set me back. So I have a last appointment with her to say i won't be coming anymore. What should I say to keep myself empowered? The last time I wanted to jump out of my skin and run away because she was bickering with me about petty details and being judgemental and opinionated. I wished that i walked out and said how bad this was for me. I wrote a letter but I think i would be giving her too much. Thanks!
