It sounds like you're saying there must be something you're presently not aware of, that you need to become aware of "or else". What's always worked for me has been starting from where I am, not where I'm "supposed" to be -- so the last thing I'd want to do would be to start struggling to experience a "sense of who I was".

I might start by noticing exactly how (or even if) I experienced it as a problem, that I didn't seem to be experiencing anything like what my therapist had asked about.

If, when you look, you find that you don't actually experience it as a problem, would you still want to work very hard at "fixing" it? If, on the other hand, you find you do experience something as a problem (and not just because you think you should, or because someone is suggesting you should), then simply continuing to notice just what you're experiencing will almost inevitably be your best guide through that particular experience.*
