Tribunal tomorrow?
Good luck, Grockle. Soon over and you will have done your best. Hoping for a good outcome.
Try searching for 'relaxation hypnosis' on YouTube. Or meditation, visualization, or guided relaxation, etc.
Someone named Jody Whitely is okay, bit of a weird sounding voice but does the business.
Also the NLP magic channel on YouTube, did I say that?
Meditation for Moms is quite new age but then, so am I. 
And also try yoga nidra search, it is progressively relaxing the body. Bliss.
Stop me if I start to repeat myself.
