So sick and doctor doesn't know why!?

Tina

I'm 27 weeks and sick as a dog! I can't keep anything down. Not even water. I'm severely dehydrated and can barely pee. Everything either gets thrown up or comes out as water diarrhea. The doctor can't figure out what's wrong and all the anti nausea meds I have been put on don't help at all. I've gotten so weak it completely drains me to raise my arms up to get a plastic bowl from the cabinet. I don't know what to do. If I have to go on like this for 13 more weeks I think it's going to literally kill me.

Anyone else going through this? Advice?
