just me, but i would seek professional help had i had to deal with a narcissist as a parent. just as i did from being physically and mentally/emotionally abused by my ex. i had lost the sense of self. had no idea who i was anymore. took the help i sought to untangle the false information. had no ability to do it alone. had i experienced the narcissist parent i am sure i would have done the same-sought help knowing the "scars" i had.
by getting help i learned who i was and how to like myself, learned to value the strength of my convictions-had lost this ability, and also how to avoid having this type of person in any relationship with me again by knowing the "red flags". i never wanted to be "jailed" again. today i am free, joyous, and happy. it was well worth this the journey to freedom.
