I highly doubt my T has discussed me with anyone else or gotten supervision (I don't think she even has supervision).

Basically, because I highly doubt she's invested enough in me to do that -- I don't mean that in a bad way at all i.e., I actually find it highly comforting that she's so hands-off and doesn't seem to at all get concerned about my progress (or the lack of it).

I also don't think I am anywhere remotely near a sufficiently complex psych profile for her to think she needs help with me -- she appears to have a rather stellar opinion of her own abilities.

She's also a solo practitioner who works only part-time.
