Lovealways86, and welcome to the family!
I feel with you both, I've been there. My mom was high functioning too. Nobody who met her at work or in public would ever have believed what she was like at home. I guess it was her way of coping, she built up this whole other persona and left her problems at home. Needless to say that left us who loved her in equal parts neglected and subject to rage.
Other passions become an escape, I suppose, so high functioning can also be very high avoidant. You can't change her. But working on yourself and centering yourself in your life, ironically, is one sure way of getting their attention. When she sees you've stopped running after her, she will come fetch you, don't worry. Any hobbies or people you've neglected lately? Now is the time to get back to them.
