Why do you find asking your therapist a question that is really more about you than anything impossible? Why do you assume she'll take it as a criticism? All you are asking is whether she finds your history uninteresting and/or if she feels there is more to your history than might need to be explored and what that might be. It isn't like you are telling her she is doing anything wrong, and even if it were, that really isn't unusual for a therapist to hear. You are simply telling her how you are perceiving what she is asking and how she is interpreting things, and you are wondering if your take on that is correct or if perhaps she can clarify what you all have been discussing in session. That sounds like pretty normal therapy conversation.
