That is one of the most perfect responses that I could imagine.

It reminds me of a time when I was invalidating my emotions and responses in session (as usual), telling T that I had no "right" to feel the way that I do.

T said:

"There is no right. There is no wrong. It just is."

That has really stayed with me.

I hope that you let your T know how signficant here words are to you. As far as using the word the F word (lol), I don't see that as unprofessional (obviously not b/c it comes out of my mouth, like, five times per minute in therapy). I think that the fact that you felt the meaning behind that simple word is because your T used YOUR word-- and that is even deeper evidence that she is listening, that she is joining you, that she is in this with you. Sometimes all it takes is one word.
