I'm not sure Anthony. I know that therapists or social workers that specialize in mental health can diagnose but cannot prescribe medication. In my situation, I saw the therapists for therapy sessions once a week. I saw my psychiatrist everytime I ran out of meds, like, once a month. She would only ask if I had any side effects from the medication and about my physical health. So for me, a therapist is a mental health counselor and a psychiatrist is a medical doctor who specializes in mental health meds. I'll have to look that up...got me curious.
