If what jexa says is the case (which seems most probable), I can totally see how this can be translated into sounding like she (your T) doesn't believe in you. I can say I would have translated it in the same way. I would jump to... well she doesn't have faith in me. Do you think it would be helpful to ask her to clarify:
Do you mean you don't want to comment because you don't know what I am like outside of therapy?
Can you see how I am easily translating this into your saying that you don't want to comment, not because it is a part of me you haven't seen, but because you don't have faith in me?
In essence, don't we all want and need the unconditional faith in us that our parents were SUPPOSED to provide? Isn't it natural to look to T for this. I know that I want my T to say, "I believe in you. Yes, I believe you will be successful in your area of study." Not beat around the bush...
Oddly,
Very often my T will say something to me like, "It's not like you're expecting to be CEO of a huge corporation in two years."
I guess she says this to point out that I am being relatively reasonable in my goals. But I have to admit that I even find this little exercise in "keeping my goals in perspective" to be somewhat hurtful. In the back of my mind I'm like, "does she really think she needs to remind me not to think too big?" (When in actuality it would probably do me some good to feel for once like the sky is the limit).
