I am thinking about going to see a Psychiatrist. Not sure if it's a good idea or not.
This is a doctor  who specializes in psychiatry
Can they prescribe medication because I might need some?
the branch of medicine devoted to the diagnosis, prevention, study, and treatment of mental disorders.
I've been feeling really sad about a lot of things so maybe I should talk with someone. Do I just talk to them about it?
They evaluate patients to determine whether their symptoms are the result of a physical illness
If I just need to talk to someone who I see a therapist instead?
psychiatrists may employ a mental status examination; a physical examination as part of their work process
