My long-time psychiatrist is in his early 70s. I adore him and appreciate his knowledge and experience. I have had younger and female psychiatrists in IOPs and inpatient. Most were just fine. Some were clearly more knowledgeable than others. Some were more caring than others. I'm not fond of psychiatrists that aren't. I think that's reasonable. Don't you?
I have had so many therapists over the years. It's been a rocky road for me with them. During my sickest years, I might have been part of the problem, but in later years, it just seemed to be either bad matches or they were the main problem (I won't go into all of that). I much prefer therapists that are around my age (again, won't go into). It is best that the therapists be female for me, though I have had some issues with female relationships. I very much like and respect my current therapist. I feel I am making very good progress with her. She's a psychologist that's likely my age.
When it comes to therapists, I have much preferred psychologists over social workers.
My long-time psychiatrist (probably 25 years older than me) has scolded me for wanting to avoid social workers and female therapists (at times). He also scolded me once when I said I wanted to avoid therapists younger than myself. He was absolutely right that a female therapist was best, but he seems to have been dead wrong about the psychologists vs. social workers, and my therapist age preference. He doesn't exactly scold me for having a male psychiatrist that's 25 years older than me
