"I see... and how long have you been experiencing these problems?"
That guy.
Psychiatry is a medical profession, you would be studying mental disorders and the biological makeup of the brain. Of course, you'd have to understand human behavior, personality, etc, but you would more so be working along side doctors or psychologists who reroute patients to you so they can get medical treatment. There are psychiatrists who rarely ever see a patient outside of giving them their prescription.
I mean, not that it isn't a good field, it could use people who care for their patients, believe me. But you seem to be looking more for a hands-on field, actually studying people and their mind by talking with them and helping them sort their issues, yes?
