Button pushing Mama...

What is it about my mother that still pushes my buttons?  I want so desperately to have patience.  Each day as I get up I just know that it will be the day that I am patient.  But, all of things that my mother did that irritated me throughout my life are magnified.  Intellectually I know that it is the disease that makes it worse. But, emotionally it is still the same old manipulative behavior.  And I am at a loss on how to separate it.
