Generally speaking, one only goes to a psychiatrist if you need drugs. If you only need to speak to someone, you generally go to a psychologist or counsellor. Difference being (as Danny said) that the psychiatrist can write prescriptions. Often times the psychologist will refer you to the psychiatrist if they feel you need drugs. And you'll come back to the psychologist for the therapy sessions. Of course the psychiatrist can do both, but it's also generally more expensive for their time.
