Do you understand what a narcissist is? What's your understanding of this

My mother is a malignant narcissist. She lies, steals, manipulates and back stabs, all while playing the victim. I tried to commit suicide at age 14, and the first thing she said was ‘How could you do this to me?! Do you know how this is going to make me look in the community??!’

Yeah, I have a decent understanding of them.
