The best way to deal with a narcissist is to not rely or depend on them for anything (financial and/or emotional). By relying on them, you give the narcissist the power and control they desire. You are indebted to them and they will not pass up the opportunity to remind you. With narcissists, everything in life is conditional. The life of a Narcissist usually ends on a bad note. After a lifetime of bad and abusive behavior, everyone ends up eventually cutting them out of their lives.

Me personally, I'd rather live on the street than put up with emotional and psychological abuse from my sick and twisted narcissist mother. My advice is to keep your distance and open up to other people. These are people you may be able to rely upon in times of need (rather than your narcissist mother).
