Children of narcissistic mothers yearn for true, accepting love from their mother and what they instead find is a person who has no idea where she starts and where her children end. She has no idea of what her identity is outside of manipulating and controlling her children and conveniently wears the disguise of victim just to invoke sympathy and attention from others.
The narcissistic mother may not have been secure and loved for who she is but since her ego has unmet needs and a tendency to want to prove others wrong at the cost of earning her rightful place which she assumes is by projecting a false sense of self and brainwashing her kids to hero worship her while slips her true personality under all the drama which she creates over and over until people believing that it's true - the truth is that they can't stand to face themselves and need others shoulders to push their responsibilities on and if they don't seem to match to her expectations, then guilt trip them and keep them in the fog and blames them for lack of their responsibility to take better care of her. She intentionally does this so that her own children get projected in the wrong way so that she wins this battle, this competition, this war, so that she survives by wearing her children out, by dehydrating their spirit, and keeps score of how much to give back in unnerving, destabilizing, and overshadowing ways in case she senses that they are on the winning side and have control in their hands, and all the while living in the pretense that she creates that she is quite adaptive to her children's decisions and will support living with them.
She cannot live apart and needs her children to live through them. Narcissistic mothers need to feed off their children's open mindedness and has to find a way to fit in even in the smallest spaces that separates her from her children. Children of narcissistic parents need to develop more self love and empathy for themselves for coming so far with their mothers that all the time, opportunities to explore and have fun in their own ways separate from the intertwined web of living with their mother seems to have gone and there's nothing that could have been done to undo all the time gone by.
The inner landscape of children of narcissistic mothers is a dried and saturated space which has their mother's presence written all over it - narcissistic mothers can exploit the concept of motherhood to get what they want and go to whatever extent they want to make sure they stay in the center of the child's attention span. The children have to become the grownups in order to accommodate their narcissistic mothers at the cost of giving up on experiencing their childhood and all those precious experiences which would have made lovely memories that go well into adulthood and beyond.
Being securely attached to a narcissistic mother is next to impossible as she needs you, your innocence, your energy, your trust, your spirit, your attention, your kindness, your time, your life, and your everything in it to sustain her. Feeding her off off you is going to disempower you as the child of such a parent and the more you step into your gut instincts, your intuitions, your nudges, your restlessness, your spontaneity, the better chances you have to organize your life around yourself. You need to keep reminding yourself that your life matters and your priorities in life are different than what she leads you on to believe.
Let her live under the impression that she is your omnipresent, omnipotent God, and she has gone through whatever she has gone through to make your life what it is today, but never allow her to soften your will. Your will is your power. Don't let her break it and use it against you. The trauma is not in the weakness she makes you believe you have(be it physical, mental, financial health) but in your losing your clarity by being attached to such a toxic attachment and allowing her to win, to control, to manipulate your life and which only adds up to losing a sense of your self, which is a far greater loss than any of these.
Narcissistic mothers need boundaries while you need your balance. Your perspective of what life is for you matters and not their defining you on their basis of what they see is fit and right for you, because what was right for them at some point in time need not be right as time progresses and you start to grow - not for them but for your highest good which would ideally make them feel good and not the other way round - using their children's will manipulatively against their knowledge to get what they want and grow off their separate roots and make them become dependent on them unconsciously.
Living for yourself is not a crime and so don't feel guilty if you begin doing so. Self love is not an antidote against narcissistic mothers, but a healthy means to gradually and slowly connect to oneself piece by piece day by day.
You don't have to pay the price for being created by a narcissistic mother, but stay enough motivated and energized to want to invest in yourself and your dreams no matter how small or big it may be. Because it's finally your life and if you don't get to have a say in it, then who does?
