Oh yes, I can absolutely relate... I guess, I posted a similar thread few days ago when I wrote that my T started talking to me about me in 3rd person

Because my T also talks about different parts of me and wants even to "talk" to them
And I hate it, I always say that I am only one and my T always has to agree that I am one but there are many parts in me

And okay, I can agree with it till a certain degree that sometimes I am very defensive even when I don't want to, or for instance when my T asks how I am doing and I say "good" while a part of me wants to scream

So for sure human brain is complicated enough to have different feelings at the same time which together create our personality...
Unfortunately I do not have any good advice for you but I've negotiated with my T that she won't talk to me about me or ask direct questions to any of my part separately but that she can ask what all my feeling/thoughts about something are, if I have any inner conflicts about something etc... This I can stand somehow
