As an engineer for many years, my brain is really attuned to, and good at, understanding how systems work - so when I became a therapist, it was natural for me to see the brain, body, energy, beliefs, behaviours, etc., all as a system rather than discreet functions.
After about 20 years of working with complex OCD (and my own full recovery), I tried to put everything I learned into a metaphor to explain what might be happening.
I hope it makes sense!
