I can understand that it might sound like she's saying that you don't need to be there. That would be good to talk to her about directly.
I think she meant that as an expression of acceptance as well as the idea that, in spite of a diagnosis, a person is who they are and that is okay. That doesn't mean there are not many many things to explore in therapy and ways to make life feel better.
What could be 'wrong' with being who we are at any stage of our life.
