Needing some supportive words...

I am trying to deal with Mom's decline (or what appears to be decline...). She has been crying more and more -- sometimes for hours (no tears). We have started giving her Lorazepam more often (small dose). Even after an hour, she was still crying. The doctor said he cannot make a diagnosis as to why she is crying because of her cognitive state. So, he told us to give her the Lorazepam 3 times per day to see if that helps. My SIL told me she would write her Mom notes (she had dementia) because she would respond to that. So, I tried asking Mom questions on paper, like: Does something hurt? Why are you crying? To the first question, she said, “No.” To the second one, she started crying more…. That was two days ago. Now she doesn’t respond to the notes. She does appear to read them, though. She spends much more time laying in bed (not always sleeping soundly), or in her chair doing the same. But, when she is awake, and in her chair, she wants to constantly get up and walk somewhere. She cannot walk unassisted. To top all that off, my brother found, what appears to be, an enlarged lymph node near his right clavicle. It could be an infection or something worse. But, when I asked him if he was going to call the doctor, he said, “No.” He has an appointment with his oncologist (a scheduled appointment for the CML), so he is waiting until then…. He also told me he is at the highest setting (5) on his oxygen machine. He started out at 3… I never know what I am going to find when I get to their house in the morning…. Sometimes I feel like they are both going to pass around the same time… As the saying goes, "God only gives you what you can handle...." He must know that I can't handle much!
