My Fiance Is Female 53. SHe Was Hospitalized With Pancreatisis

My fiance is female 53. SHe was hospitalized with pancreatisis in March 2015 and since
has had to watch her diet, and she has not been right since About a month ago she fell into depression. Over the last 10 days she is so nausueas that she can at most eat 1/2 a banana and a few cheerios a day, and maybe 16 ounzes of water. SHe is up all night, lost alot of weight. Going out to the supermarket is too much for her, after a few minutes she gets so anxious she has to wait in car. She has been to emergency room twice in past week but they dont do much for her except change meds around . SHe hallucinated a few days ago, and today is the worst. Hardly any sleep all night and crawled up in a ball on teh couch all day trying to get some sleep. Nothing to eat or drink, thick mucous in her throat is bothering her, headaches BP elevated
