I travel for my work and am gone 40+ weeks/year. This leaves the care of my elderly mother to my 2 sisters.
Needless to say, they are very upset that I am not able to contribute much. My work is very demanding, and even the weeks I am home, I am working in a very busy call center with poor staffing, making it difficult for me to leave to make doctor appointments and things with my mother.
I understand their anger at me, but just don't know what to do. I have tried having my mother stay with me when I am home and she is not happy doing that. She lives with my older sister, and the primary burden falls on her shoulders.
