5 Weeks Ago I Fell Very Ill. I Went To

5 weeks ago I fell very ill. I went to my local hospital. they put me on a drip. Did an ultrasound looking for kidney stones? And an xray. The only thing I couldn't do was a urine sample. In that 5 weeks I have not stopped being ill. I cannot eat. certain smells I just want to be ill. constantly thirsty. Every evening I feel so Ill. My last child was 20 year ago.I am 43. Haven't even thought of having another child. My breasts have been so barren for so many years. Last night milk was leaking. I am diabetic 2. I took a pregnancy test it returned negative. I am lost as to what it could be?
Any advise would be appreciated.
Thank you.
