Do you tell the therapist about your joys and triumphs?

I said "sometimes". Like some others, I would not use the terms "joys and triumphs" to describe my successes and positive experiences but I did tell my Ts about the latter quite a lot - it makes sense to share accomplishments and solutions with people I see because I have problems. I also much more effectively tend to bond with people via sharing positive experiences and good solutions than sharing misery - just my personality. I easily notice that even on an anonymous forum like this in the patterns which members I feel drawn to. So, yeah.

I find it hard to do so. I was seeing T2 when I completed and handed in a 12,000 word dissertation for a masters. I didn’t mention anything about it. I might have liked to.

I do, and T has shared that it is just as important part of therapy as talking about the bad stuff... but most people only focus on the bad. So T is encouraging me to bring more of my joys/triumphs to session.

Yes, as you probably surmised from my post on the other thread. At least some of them, sometimes.

I'm sure it depends in large part on what role therapy plays in your life. If I were there to vent, I definitely wouldn't share when good things happen or when I accomplish something big, because that would be a waste of time. But I'm not there to vent. I'm there to figure out my patterns and get help changing the ones that are detrimental to me. And the ways I react to major positive moments are a big part of that, because I often react to significant accomplishments in an idiosyncratic, counterproductive way. So I'm not going to get much of anywhere if I don't share those moments with my therapist.

And I can understand how the phrasing "joys and triumphs" could seem over the top out of context, but I'm fine with it. Life can be full of both big and small joys and triumphs, just like it can be full of loss and sadness. My childhood had both joyful moments and abuse, and sharing one without the other doesn't give the most accurate version of things. My life now has really awful moments and really wonderful triumphant ones, and they're both a part of what things are like for me.
