Do you have any calming or relaxing remedies for 11 year old

[Cowey]

11 year old (suffers a bit of anxiety anyway) gets very nervous and anxious in Situations such as exams, performances in front of audience (school or dance shows)
she wants to do these things but gets so nervous that she’s nauseous and sometimes even vomits because of the nerves.
any remedies you’ve come across? I’m thinking rescue remedy for kids?
ps. She is on waiting list for cbt but could take years I’m told.

Has she tried slow breathing and also the 54321 technique (5 things she can see, 4 things she can hear etc)
Imagining and walking through what a situation will be like.

I think that teaching breathing exercises is a beneficial skill for anyone who suffers with anxiety. I didn't realise there was a kids rescue remedy but I've given my 9 year old my rescue remedy gummies before now - even if it's placebo the distraction of it can help.

No idea why my post was hidden - I've not said anything dodgy!

Yoga
Breathwork
Colouring
Baking

Mindfulness can be helpful for this level of anxiety. Particularly the distraction techniques imho.
