good for you! Yes, you mother is p.o.'ed and yes, she'll get over it. She's a grown woman. She, like the A in your life, was used to you playing a certain role. Now that you have redefined certain aspects of that role, she's angry, perhaps because she feels a loss of control over you, or a loss of support in her efforts to enable your sister. Whatever it may be, it's entirely her business and none of yours.
Doesn't it feel nice?
