sorry Moon, I thought through this but got confused...
I'd say that Ne and Si are valued functions for you, and by your discourses I've always thought you could be a F > T.
This would leave us with either a gamma SF, or a delta NF. I haven't watched your video again, I don't remember if you've expressed your approach to your surrounding, or the things that set you in motion, I mean, I have a hard time figuring if you're an Extro or Intro-vert.
For the way you look, your self containment and general manners, I'd say you could be an Introvert.. but perhaps an IEE can be similarly "quiet".
The Psychologist is an archetype fitting both Delta NFs, sure, everyone can be, my ENTp cousin is a psychologist too, as was Aushra, and many other ESI or NFs or whatever, everyone can be everything.. but, if you have that kind of attitude, perhaps that fits to the general idea of the NF, who likes to help people out rather practically.
I don't want to push a type upon you, but I wanted to say since the scratch that you look just like one of my mbti INFJ besties, I have no idea how to convert her into socionics, I think she's in between j/p.
