I am glad you were able to find the root cause and get treatment, and sorry you had to go through this. I hope we will soon remove “psychiatry” from the domain of medicine completely and start addressing actual biological issues directly.
The interesting bit here is that getting to talk to a psychiatrist was one of the main things that "excited" me about getting checked into a psychiatric hospital. My understanding, at the time, was that they crossed the lines between biological and psychological. A psychologist with an MD, if you will. That seemed, at the time, like exactly the kind of inter-disciplinary doctor that I needed.
There was no psychiatrist that I could see at the ER as far as I know. I had to get checked into the psychiatric facility in order to see one. So that was another dimension here where I was enthusiastic about going, and probably made the decision by the ER to send me there easier.
