Should I cut myself off from my mother?

My mother is a narcissist. For years I have suffered under her control, and developed a codependency with her. I have been in therapy for a few years for this, and we have worked on things like individuation and coming to terms with my abuse as a child. However I still find myself preoccupied sometimes with wanting to make her happy, and wanting people to love me, and other codependent tendencies. Would it be beneficial to completely cut myself off from my mom, block her e-mails not answer her calls, etc?
