Nononono, you're thinking of PSYCHOLOGIST, NOT psychiatrist! Psychiatry is all about medicine and biological factors; the majority of psychology is based on therapy and counseling. BIIIIIG difference, BIIIIIG difference in schooling, and BIIIIG difference in money! XD
So, consider Psychology and Sociology. I'm currently majoring in Sociology and minoring in Psychology. I love 'em both! You may also be interested in Anthropology.
