Thanks, D! That's putting it mildly.
Tests are inconclusive so far, though it seems heart related. The pulmonary dude and heart dude are visiting and doing their things in the morning. Pneumonia has been pretty much ruled out, as she doesn't have any of the other symptoms. Hopefully we find out more tomorrow after the tests.
I'll try and visit her in the late morning. My two Beanie Babies will be going with and will watch over her again. Yes, I have two. Make fun of me or them and I'll pound you into the ground. Mom bought them for me when I went through a couple of rough spells.
