You need a plan. An ER isn't equipped to give the support you need.
Depending on your insurance get a good Theripist. A good Pdoc too for meds.
Then you take charge. Make some notes. Tell them these are the topics I'd like to explore.
These issues make me emotional. Angry,sad,depressed,disrespected.
Find support groups free thru organizations like Nami.
You should be happy. If you are being mistreated it's wrong.
The experience you had was unprofessional on their part.
Don't wait till a crisis comes up.
