Well, almost exactly a year after my father wound up in the Intensive Care and only barely getting out of it again, now my mother has to stay at the hospital (though in the normal wards, thank god).

Situation seems stable right now - the doctors suspect some kind of infection, they suspect it to be related to her left leg (history of trouble with thrombosis and type 1 diabetes-complications), but it might also be pneumonia.
She's getting a antibiotics-treatment now and seems stable, but it's still simply hoping that the situation won't degrade the way it happened to my dad as well.

So yeah, nervous as hell...
