Those of us whose earthly mothers are less than optimal are very grateful that Christ gave us his own mother at the cross.
As far as the other saints, I consider my patron saint, Martha, as my spiritual Big Sister. I converted as an adult so got to choose my own, as opposed to having one chosen for me as an example by my parents. I chose Martha because I too am easily led away from spiritual concerns by earthly ones, and since she overcame that flaw to become a saint, I have hopes that her assistance will help me to do the same.
Nina, that is very nicely phrased. I too am often overwhelmed by earthly concerns, so I understand why you chose the patron saint you did.
St. Martha would be proud of you, I think.
Regards,
