Hi Ousaima,
that's a good collection for the start!
Which ones have you tried successfully, or what are your favourites?

For to create distance, I also can use a breathing exercise, or the Eagle position, or an imaginary shield... 
For resourcing, we can use modeling/mirror neurons if the client believes to lack the resource. Modeling is learning by imitation, that is close observation and imagining lively how this attitude feels.
For balancing, we can activate the other brain hemisphere, or alternate between them like in bilateral movements (walking, dancing, paddling, juggling...), especially when crossing the midline of the body. There are amazing exercizes with balls, excellent training for kids! [https://www.bal-a-vis-x.com/the-exercises] 

Anybody who wants to share more tools and methods?
