There are now some coaches on YouTube that are very helpful in advising on how to cope with an emotionally abusive parent. In the household of a covert malignant narcissistic parent, children get assigned roles: the scapegoat and the golden child. To save you wasted years of your life, you will never be able to escape the role that you have been assigned. Even if your narc parent were to destroy your life, she would still find a reason to blame you for something or other, and play the victim.
You have to go 'no contact' or at least minimise contact as much as possible (minimal contact still counts as maintaining silat al-rahm - just at a safe distance). You will not be validated or have your true self seen by your mother, because she is invested in invalidating you. Instead, you have gradually accept that she will never be the mother you wanted and needed, and start to find yourself again and build your own life and identity independently of her. Don't share anything with her about yourself. Keep your life separate and private. If you are still living at home, it would be advisable to work on physically separating yourself and leaving the home.
