Just dehydrated

She threw up last night, no warning.  I was just resting next to her when I heard a strange noise, pretty sure what it was.  I sat her up and got her daughter.  We got her cleaned up and changed her jammies.  She kept complaining that she hurts and she was cold.  Her family ended up taking her to the hospital, to be sure, because sometimes Mrs. D just doesn’t know how she feels.  They were worried it could be pneumonia because some of the pain was in her back & chest.  She was having some difficulty breathing too.  Ended up just being dehydration.  She isn’t eating much either.  I admit, while praying with her, I told her it’s ok to go home, that her family will be ok… because they will be…Is that wrong?
