Not knowing the context, obviously that doesn't sound helpful. BUT: It's been said about me, too, by my T's. (And others. Everyone). He probably didn't do well at getting his point across well and with the intended effect.

I wouldn't take that as a negative thing (again, not knowing more context). It sounds, as someone else said, merely like an observation. It's also personal to him. Probably some others find it easier to connect with you, some less. If you were more similar in some ways for some given X's, X=[x:x ~ culture, level of intelligence, religion, values, etc.], maybe it would be easier for HIM in particular. Connecting is a 2-way street.

You're not a failure. You're just so far from the median in certain ways, e.g. intelligence, trauma history, etc. that the number of people who are enough "like" you is smaller than for most.

You've been a great success lately in very important ways.
