Loving Daughter

My Mother turned 80 years old on April 7, 2008 and I see a big difference in her. I am one of nine children and I don't know how my mother has kept her faith, hope, and love all these years. She has lost her son age 27 killed by a train, a son by suicide (2005) and Michael age 51 (2007) from cancer. She just changed so much. I don't know how much pain she is in but I see that she is very frustrated looking for words and asking the same question to me at least 15 times a day. I answer her like it the first time she asked. I live with her and I sometimes feel over my head. I know this is going to be an up road experience for me. She just went to the Therapist for an evaluation and the Doctor said that her short term memory is pretty much gone. I still am awaiting for Doctors report. I guess what I trying to say that I am in denial and I am scared.
