So my mother has never actually been diagnosed with NPD, but through my own therapy I've learnt that she has narcissistic qualities / traits ..
While I've found she's particularly "worse" when interacting with me, she can and does exhibit these traits around my other siblings.
Why question is, how do you guys deal with narcissistic mothers?

I'm only seventeen, nearly eighteen and I live with both parents, so I can hardly cut off contact.
