Plenty of mind-numbing background music, but still worth checking further to see whether these "animated teaching videos for ESL and EFL learners" (About Us, ¶1, 2017.02.24 [JST]) might be suited to particular learners' needs
"Teaching communities can be incredibly nurturing, caring and supportive of the children in their care, but sometimes forget to extend this to the teachers who are at the front line. Teachers may be afraid of being seen as weak or struggling if they open up about their challenges or difficulties. My first piece of advice is find a colleague you can open up to and can offer support or just a listening ear, of course, you can do the same for them. Building and nurturing positive relationships is one of the most important things anyone can do for their well-being."
