I live with and care for my 89 year old mother with Alzheimer's. As many of you know, it is incredibly stressful and exhausting. My girlfriend, who is the love of my life, has been a saint, and really worked hard to help me during this difficult time. But she has finally given up and left me. I am not angry at her. I understand the enormous strain it put on our relationship. But I can not abandon my mother as long as I can continue to sufficiently care for her. This situation truly is the most difficult of my life. There is no justice in the world.
