Looks like I'm in a minority!
My T is a very recent graduate from her clinical psychologist doctoral program. Other than her doctoral internships, she's only had about one year of experience.
She's under 30/ exactly 30 years of age. I'm just past mid 20s so I'm the same age range as her.
She seems to know herself well, is good at portraying confidence, but I don't know about her life experiences.
I'm scared of older clinicians however, so her youthfulness suits me. I wouldn't want someone who is motherly, but I like how my T can be like I slightly older mentor / guide.
