Wow, that sucks.

You did the right thing and are accused of something illegal. Well, maybe not but all but.

You speak of trust. I would, too. I'd try hard to trust myself, did I indeed did no wrong. The evidence is you did no wrong. It’s only when you talked to the therapist did your trust ebb. Fight to get back to there.

Then there is the question of therapist client relationship. I would understand some level of distrust with her. I would push to resolve it or cut ties. In this situation, I could imagine holding back because of the distrust, telling something short of the whole truth. As a matter of fact, I've been guilty of holding back because of trust issues. That did me me no good.

It looks like you are in a tough spot. Hold on to the truth that you did no wrong and trust yourself.
