Lou, My heart goes out to you...cause I know what your going through, My Aunt just passed away last week with it, and my other Aunt(raised my dad) that lives across the street from me has it and now my dad has been diagnosed with it...It is so hard and scary when your doing it all yourself...My Aunt has kids but none that are close to her and its just me and my sister for my dad, my mom has RA and we are worried about her also...It really sucks for your parents to get older....but they took care of us, so now its our turn...I am here for you if you ever need to talk....
