Neither the death of N, C's mother, nor the death of B, T's mother, was unexpected.
N had diabetes, major circulation issues throughout her leg, chronic low blood pressure as a result. I think what killed her (though I don't know details for sure) was heart failure due to circulatory system collapse.
B had cancer, and the chemo was making her more ill, so it is no surprise that the cancer just overwhelmed her immune system.
The mammal I married is doing distinctly better, lot of the swelling in her leg has gone down, the seriously heavy duty course of antibiotics is doing the trick there.
Oh, the offspring unit went in today to see what the heart monitor she's been wearing for the past two weeks says. EKG and all that. She gets the treadmill test for her birthday next month.
