I always asked myself that question.... I take care of my Mama. She has four grown biological children that take NO part in her life. I know that if I was not here to take care of her, she would be in a nursing home. She is not long in this world and I will miss her, somehow, I feel like my life is waiting to start after she if gone. I love her. I will miss her when she is gone. Even with everything I do for her, I am scared I will feel like I have failed her and it will be my fault she died.
