This won't apply to your situation but...

Yes, I used to write a lot. I would give the writings or letters to the different T's I was seeing at the time. That stopped during the malpractice case when AbusiveT used them against me out of context and copy/pasted with pages missing during the lawsuit. All his lawyers read them. My lawyers read them.

I will never do that again.

Now, if I have something for present T, I write on my iPad and take it with me to therapy. I read it to her or have her read it. We don't email, she doesn't have any writings from me.

If I didn't have an iPad, I would write things down but they would leave the session with me.
