First - congrats! I know you probably didn't intend to expose the scary hard topic, but now that you did, I can understand the mixed feelings - elated and vulnerable and uncertain - all at once.
Yes, it is probably something that our Ts experience a lot - a client's biggest fears come out, and T is ok with it. Doesn't stop me from needing to check in to make sure T is still T, and she still likes me, and everything is still good in our relationship.
Doesn't stop me from swirling out of my mind - did I say too much? How could I let that slip out? Why do I feel so much lighter? What if I said too much? Then I ruminate over that until I next see T, and we spend the session discussing the previous session's disclosure, where T repeatedly reassures me that there is nothing we can't talk about and yada yada yada.
The thing is Cat, to us it IS for sure a big deal. And our Ts know that. They are able to hold it differently and see it differently in a way that allows them to validate how huge "it" is for us, without letting "it" overpower us anymore. The odd sense of freedom from that secret is somewhat uncomfortable at first.
(Speaking from experience - just had a HUGE revelation two weeks ago, shared something with T that I've never shared with another soul, and I so did not plan on sharing it with her that day, it just slipped out. It is still unsettling for me to hold on to, but it is somewhat comforting knowing that T now knows one of, if not my biggest secret. It's given us really good stuff to work on, and the last few weeks since the revelation have been hugely powerful - all the more reason I'm melting without her this week.)
You've done great to reach out here, and even better to share it with T. I know she doesn't think anything bad of you, and if you were to reach out and send a quick email telling her you're a little freaked and just want to make sure she's ok with things, I bet she'd understand
((((Cat))))
