Alzheimer's threw somthing at me last night....

Well, I say Alzheimer's, because I refuse to say that my grandma, threw something, and hit me last night. My mind knows it was the disease, in fact I had read that it can happen, but it catches you off guard when it first happens, because your looking at this familiar person, the person you love, yet you know it is not them. My grandma was refusing her medication, this was a first as well, she was scowling at me, and saying "Why should I listen to you, you are not my Dr!' I tried everything. I had my mom call her, and try to reason with her........ you can not reason with a disease. Then I called the nurse on call, and she said to deliver them at the other end, which is near impossible when she wont let you give her a hug, much less go that route! So at last, I had come up with an idea. If it was a Dr. she wanted,  it was a Dr. she would get. I called my sissy explained what I needed her to do, and soon Grandma's phone rang. I answered it in front of grandma, and said " Oh hi, Dr. Nelson, Opal? Oh yes she is here, just a minute." I handed the phone to grandma, where my sister pretended to be the Dr. explaining that she had sent her nurse (me) with her medication, and it was important she take it. After TWO full hours filled with things thrown, a hand raised, and my patience at its end, she got off the phone, and asked me kindly for her meds. She then proceeded to take them as if she had wanted to all along. You might wonder why are meds so important, just skip it if it becomes such a fight. Well when she has severe delusions if you don't give her certain meds she will stay awake all night talking to people who are not there, sleep the next day, and before you know it, nights turn into days, and days into nights. I am still reeling from it, my mind knows it was not her, yet my heart hurts so much. I hate the vacant look in her eyes, the distant behavior, and her ability to be so cold to me. It's a grief cycle of it's own. I just wanted a hug all day today, to be told it would be ok, to be reassured that it wasn't all for nothing. That she knows deep inside how much I love her, and what she means to me. What God is giving me the grace to do. So, if you can just say a prayer for her, and I, and this situation. For grace, patience, and a understandng that superseeds the reality that seems to be.
