Also (I'm not in therapy and almost certainly won't be again) I find that even in everyday life similar issues come up. I have a large number of teddy bears - donated by people who knew that I didn't have toys as a child or compulsively rescued from second hand shops - and they are part of a consciously created inner storybook that I find nourishing. I tell stories about each of them, and tell stories to them - and all those stories help me to grown and recognise my inner world.

Someone recently ventured into the private parts of my house to repair something and made what seemed to me at the time like a vicious, critical comment. I was so enraged that I literally wanted to Bite Him! 24 hours later I had calmed down and realised that he just made a flip comment. His personality is to be combative and wait for something combative to come back. He's not mean. it wasn't meant personally.

We (all the versions of me) are sensitive about personal criticism.
Reading your post it occured to me that we learn to define ourselves by asserting our differences... and getting comfortable with ourselves. Perhaps this could be a growth moment in your therapy where you get comfortable with what you know, even if that's not what someone else knows?
