I became really ill after having operations and developed a kind of psychosis in the hospital environment. It was scary. I think it was to do with the physical problem (is meant to cause 'altered mental status' also not being able to eat for a long time, or sleep, all contributing. Although I still feel a bit muddled as to what went on, (I thought the nurses were all talking about me during the night shift but they were probably talking about the patients in general- it was quite loud though) the hospital didn't deal with it very well. I distinctly remember a nurse telling me 'we can't deal with your kind of needs in here' and another laughing to the others after I'd been frightened by the hospital helicopter noise at night (it has a launch pad on the hospital) I understand they're busy but the could have been a bit more understanding.
I started refusing medicine too and nearly refused a life saving operation, thankfully my husband was there and talked me into it. I thought the IV antibiotics were acid they were trying to poison me with and refused it after several days.
Has anyone else had a similar experience while very ill? I have since seen a psychiatrist who said I'd had "depression with psychotic features while under severe physical stress.
