I was an ER nurse for years. I will be direct. The staff are not trained to deal with mental illness. The remarks and subtle judgements, such as, " Well, you can't expect blah blah blah. Bologna! I am on a cell phone and was unable to read the above. ER understands severe crisis. I only will go if I am dragged or have become psychotic. And my psychiatrist agrees It is a sign of our failure to care for and respect the mentally ill when we feel our pain so severely we we can not bare it. They don't know the studies that show emotional pain fires up in the same region of the brain as physical pain. It is PAIN.
YOU ARE NOT WRONG. The system failed you. And it will again, so work with psychiatrist for future plan.
