Hospitals

I’m playing a doctor at a psychiatric hospital in a play, and my character has no description whatsoever in the script, so I’m building it on my own. First I wanted to find out more about what my character’s traits would be because of their profession. What kind of characteristics, like attitude, mood, things like that, would a doctor working at a Psychiatric hospital have?

Also, in the play it is a very upscale expensive Psychiatric Hospital, if that would make any difference.

I worked in a psyche hospital
our doctors were always calm, never rattled,never alarmed when a patient went off. often annoyed or frustrated
they were never happy go lucky, or talkative or funny witty or engaging. They would listen alot -like at lunch, but rarely add to the conversation
