4thing NF
Neuroptimal is an idiot-proof form of neurofeedback -- and a good beginning. A machine costs 10K but cn be used infinitely. It is rentable for about $2K. In my town NF sessions are covered by MediCal through a CBT therapist who does it. It is great for overall calming.
My CASA youth turned her whole ship around after neurofeedback. It helps with self regulation. It helps with insight. She used to dissociate prior to NF and that ended after.
Very non shaming... that your brain can adjust itself when given feedback about its own activity....
