Hello SoConfused623: This appears to be your first post, here on PC... so welcome!
The Skeezyks has some experience with regret following disclosure. A few years ago now, I divulged a life-long, closely guarded secret. It turned out that no one really cared to hear about it & pretty-much just ignored it. As a result, it caused me to regret having ever talked about it. The experience left me feeling exposed & foolish.
Since you had this experience with your T, perhaps the best remedy might be to talk with your T about what you're feeling. Your feelings are completely valid & understandable. And honesty about what you're thinking & feeling is the bedrock, so to speak, of a therapeutic relationship. I certainly understand the shameful feelings you're experiencing. I feel similarly. But the good thing is that this happened in therapy & so there is an opportunity to delve deeper into all of this with your T. You've opened the door. I know the tendency is to want to slam it shut again quick. But avoid doing that if you can. If this T is not up to helping you through this, perhaps it's time to find a new T.
