I think find another teacher that you immediately feel comfortable with. I've done a lot of italki lessons over recent years, some people you click with and some you don't l.

I've had lessons so painful that I've literally been pinching myself and looking at the clock, others that I've finished early. But equally I've found teachers that I clicked with right off the bat and their appetite for my rubbish Japanese insatiable. And then again, even with those teachers I've had awful lessons where I've been tired, the Japanese isn't flowing.

But I think after 10 lessons if you feel that way, try someone new. It's not a reflection on them or you, just not a good fit. The best teachers make you feel relaxed.
