My depression also worsened as my truths came out in therapy. When it was not improving, my T helped to advocate for a med increase/change from my pdoc with me. I"m fortunate that they work as a team.

But I don't believe that it was just the med change that helped me improve. My T and I discussed this last week and it may be that I've come to see that the world will not fall apart when I tell my truths, if you know what I mean. I was an "adult" child as well and urged to keep family secrets as family secrets.

That's my story, your path maybe different. But the depression can lift if you keep doing the work of therapy. Tell your T and pdoc exactly what you're feeling as you have told us here.
Good luck, let us know how you're doing and what decisions you're making.
