Bladder cancer

My mother has bladder cancer but has got worse this week with she can't swallow her antibiotics for urine infection she has a catheter I'm waiting for the doctor to ring and I'm usually up thru the night emptying the bag but she's slowing down weeing by the looks of it as I've not had to empty thru the night and it's hard to wake her now and sometimes her eyes are not fully shut they are slightly open I'm worried her  body is shutting down now I keep  crying mum is 90
