The best way to deal with a narcissist parent is to have nothing to do with them. You are better off having no contact with them at all. Eliminating them from every part of your life helps to slack the anxiety and frustration because you don’t have to constantly babysit their ego and needs (which as I’ve stated can be ridiculous and unrealistic). The best thing a victim of this type of abuse can do is to get away from their abuser and to not feel guilty about it. They’ll (the narcissist) go out of their way now and again to try to get back in — either through social media or friends, other family members, your own kids, hell, even using people you don’t know — trying to reach out to you. They’ll play on anything they can make you feel guilty about, making you feel like you overreacted (when honestly, you didn’t, they just play on that to get what they want).
