My mother who has psp has a chest infection and hasn't responded to treatment her potassium level dropped to 2.6 normal is 4 and were giving her chewable tablets to try and increase the levels. She told the dr she didn't want to be here anymore but they said they would review her. 4 day's later they came to see her and she told them again that she no longer wanted to be here. She is trapped in a body and cannot do anything she can't feed herself and has constant care around her. I told the drs to respect my mother's wishes the same as I am doing she has that right. They have now withdrawn all her medication and we are taking it one day at a time. It's going to be sad to loose my mother but she has no quality of life and she has guts to do this. On top of all this I am grieving for my husband that I lost to cancer after being ill for only 6 weeks.
