Try telling yourself the pose is easy right before you go into it, even if your heavy thoughts are pushing you to just sit down and give yourself a break. "This pose is easy, I can do it comfortably." And then do it.
That being said, day ten for me was another struggle of a class. Fighting against old habits, coming out of postures I've been doing pretty well at holding strong through. But every class is different, and I shouldn't let myself get all hung up on how I "should" be doing, but rather, how I AM doing.
It's tough, though. Sometimes it's hard for me to tell what is me letting my body be what it is today, and what is me letting myself go easy when I could be putting in more effort. I'm letting today be what it was because, really, I've had an exhausting past few days. I'm not going to do much of anything today besides chill at home and enjoy the day.
