With my former T, I felt an immense pressure to show "improvement" week to week -- else, I felt like she got irritated / frustrated and so on.

I also felt a lot of pressure to "fill up" the time -- so, ironically, former T knows way way more (in terms of just facts / stuff that happened) than my current T who I've seen for more sessions.

With current T, I don't feel any such pressure. Sometimes, I've felt bored. But, now looking back, I think it was partly because I'd been irritated with her and I hadn't realized it and hadn't told her. And, the other part was that the "boredom" was actually a manifestation of some weird sort of fragmentation / disintegration / hollowness that I was experiencing i.e., I didn't feel like my mind / internal self was a whole and I didn't have words to explain how I was feeling.

So, it just felt like I was completely numb or rather speechless -- given how much I rely on words (and almost exclusively on words) to convey how I'm feeling (although current T is no slouch at picking up other non-verbal expressions), I interpreted that sense of emptiness as boredom because it was too frightening / strange to really get in touch with that fragmentation and let it play out in therapy (I'm always terrified that I won't be able to "put myself back" together and leave session if I don't tightly manage to hold it together through the hour).

Once in a while, I've joked to current T that I'm bored of talking about my mother and she's immediately shot back with "Your mother is anything but boring!". And, so we kinda figure out what to talk about if I'm sick of a topic and keep going.
