Ms Vancouver, I don't know much about this, but have you googled? I think you could get a lot of info (about anything) from the web. I really feel for you. When my grandmother was very sick (stroke), I saw the suffering, and we all suffered with her. I wanted to help but felt so helpless because I couldn't do anything. My mom, my sister and I and our cousins took turns to be at her side, day and night, for about a month at the hospital. Although there were nurses but we felt that we had to be there, to make sure that she was comfortable and that she got the care she needed. That month was by far the darkest moment in my life. Even as I'm typing now, i can feel the tears stinging my eyes. So when I say I feel for you, I truly mean it.
