Just a brief update. . .
First of all, thank you all so much for the kind words of support; they really do mean a lot to me.
I just went in to see if she was ready to get up and make sure her arm was okay. She has no memory of falling, said her arm was fine, and went back to sleep. So that's good.
As far as a support system; I'm pretty much it. My father passed 8 years ago, my brother died suddenly in his sleep a little more than a year ago (which sent my ma from some obvious memory issues where I felt comfortable leaving her home all day to go to work to needing me here all the time) and it's just me and mom left of our little family.
I did have nurses come in, but it just upset my mom more than it gave me a break.
I generally think I deal with it okay; and honestly, coming back here to the DIS and being part of our weird, wonderful little community again has helped me more than anything. It gives me a chance to take my mind off things while still being within calling distance when I'm needed.
If she lives long enough to get to the point where she no longer is aware of her surroundings, I'll have to place her somewhere, but until then I'm just trying to keep her home and safe and comfortable.
Thanks again for the support- I needed it.
