I found this thread extremely helpful and wanted to add my two cents even though it's been a long while since anyone posted here. Hopefully it will benefit others as it has benefited me.

It took me six months to disclose, and I did so via letter. My relationship with my T. had been cordial and friendly but still rather distant, so I was really surprised with how well it went. He finished the letter, looking sort of grave, and we went for a little walk around the building. There was a fair bit of silence, but, for once, it wasn't awkward. We talked a little bit about the issue in a generalized, intellectual way. He was very gentle and respectful. I'd never really felt supported or "held" until that session, and found it therapeutic and liberating. I think we have a lot more respect for one another since then.

I wish I'd known, and want others to know, that disclosure can be very empowering and valuable even if your relationship with your T. is just "okay."

I hope everyone is well.

Take care.
