Sounds like someone you don't need in your life! I know how hard that would be. I feel like my mom is negativity that I don't need in my life, but at the same time, it's my mother and I love her. So I know it's not easy. I would suggest creating some distance though, even if you do want to keep her in your life and definitely some boundaries. Perhaps some counseling together to improve your relationship?? I know it's tough... Good luck to you, hun!
