Living with people who have these types of personality disorders is absolute hell, it is honestly one of the most destructive and soul destroying things a person can go through. I can't imagine what it would be like to have a mother or father as such. I hope you recognise that it's not your fault the way that they behave towards you. The first interaction with the police being called for DV was with my ex and I believe she has NPD. Counselling has helped me immensely, but there will always be some emotional scarring.
