Here's a story to tell kids who are experiencing anxiety about going to school and facing challenges and pressure in advancing grades (classes). It's a common problem but if it continues, you might need to talk to school staff. If no changes come from that, you may need to consider outside help.
I know a boy who's smart and funny and who loves to learn new stuff. But ever since he's been in his new grade, he wakes up every morning thinking, "Is it a school day?"
If it is the weekend, he's as happy as a frog in a clear pond.
But if it is a school day, he's like a little bunny, shaking in a cage. And every school morning he says to his mum, "I don't want to go to school".
Let's face it, it's far better to be a frog about these things. A frog who happily croaks and jumps from one new ploppity thing to another. Scared bunnies, as delightful as they are, do tend to quiver about in cages all day.
So what is it that you would say to a scared bunny? Would you say, "Hey get a grip on yourself! Get out of the cage for Blink's sake!"
Or would you say, "Aww, there there bubby bunny, here - I'll show you how to enjoy what's out here!"
Perhaps you'd just gently open the cage and let the bunny come out when she or he was ready, without saying a word, standing close by, but not being too fussy about her. That is to say, you wouldn't crow around the bunny when the bunny decided to come out for a sniff. You wouldn't dance around singing, "Ooo! Ahh! Look out! Watch over there and please be careful!"
Instead, you'd let the bunny continue to be a bit scared. (Everyone feels scared at times, as you know). You'd make sure all the time that there was no danger. You'd keep a close eye on things. You'd let Bunny be and then be free to feel and discover stuff.
Whatever it is that you would do for a scared bunny is perhaps the very thing you need to do for yourself when you are nervous about something. Going to school when it all seems a bit too hard or too much is scary for anyone for goodness sake!
The other thing to do, of course, is to tell someone you can talk to very easily. Keep talking to them so they'll understand that you are finding going to school really ickky at the moment. They might get annoyed if you keep talking, but that's ok, because they get annoyed about lots of things. If they get too annoyed, tell someone else.
