Wow...

That seems like a violation of patient confidentiality from beginning to end.
What we share with our mental health professionals is supposed to stay with them.

When we began working together, I considered asking R whether I could make audio recordings of our sessions for my own use later, but thought better of it - like you, I thought being recorded might inhibit what I was willing to say.

Even if it's legal, it just feels intrusive to me.
