Welcome Crosie: I'm sorry you have a narcissistic mother. I can understand how her actions can make you angry. You say she moved to your State. Does she live too close to you?
I am so angry, and I don't want anything to do with her after the last email she sent to me today. She has no clue that I figured out she is a narcissist. I read the book last year and started to do things differently. Not being readily available, or not calling her as much. Then it hit the fan in October when it was the last draw with me, and now it has come to the point to where I don't want anything to do with her. I am done.
It's a personal decision whether to go no contact (NC) or limited contact (LC). Some people switch back and forth.
It doesn't really matter what label you can attach to your mom. We can't change others, but the way we interact with them and react to them can make things better for us.
BOUNDARIES will be important to you. They are for your benefit and are up to you to enforce. You can apply boundaries to emails and other communications. Some people direct email to a special folder or label the from designation as spam.
There are a lot of workshops/articles on communications skills here that can be helpful to use with anyone in your daily life. You might want to learn some of the skills, in case you resume contact with your mom at some point. Even if you don't get a chance to use the skills with your mom, the learning won't go to waste, because you will boost your emotional IQ.
When you want to share more, perhaps in regard to the email, or something else, there are a lot of listening ears here who can give you support and ideas.
Take care.
