Hey, are you ok??! 6 lessons a day?! I can't believe it...As for me, I teach 3 or 4 lessons a day(but every day!), so I manage to be fine now!
By the way, I haven't had a experience that the student cry yet. But I know teaching a candidate and other grade student is so hard for a teacher. We tend to concentrate on a candidate although we don't do it deliberately(わざと)............(＞＜）
I sometimes meet this kind of the situation. In my case, my primary student is so kind and she doesn't complain if I can't much concentrate on her......so I often sorry for her. Then I always try to talk and communicate with her. It's just a small talk about daily life, but our relationship becomes stronger by doing it.
Then, don't accumulate your stress. Take it easy for you!!
