Hi Andy,
sorry It got worse.
you did the right thing! Hallucinations are very scary and it’s not knowing what comes next. In my case it was hallucinations that turned into body jolts and black flashes in my eyes. Hopefully after the ER gave you the glucose and the medication should help you through. It is all very scary but you can do it.
do you have any close friends or relatives who may be able to spend some time with you for the next couple or days for moral support and just to keep an eye?
