I believe our T's come to care for us, and value us, and when we are in pain and hurting, they hurt a little too-for us. But, I also believe they are able to manager their feelings and you cannot "become too much" for your T when you are simply expressing emotion. That's what you are there for.

I know for me personally, I have an AWFUL time expressing my emotions. I have read things (from my journal, letters, etc) to my T and in the end he is teary and I am not. I am blocked.

So I say raise a tissue to your tears and let them flow with your T. Crying together must be validating!
