I've found over the years, that I've lost the need to know about everything within the mental health/recovery field and just do it.
As I've done theapy, things changed, and you know What, I couldn't explain that, it's just bricks organising themselves inside of me, then sometimes, sometimes days, sometimes months, I have an aha moment. Where what didn't make sense to me before, suddenly does, because it's felt. A lot of Therapy is about being felt. Words and explanations don't always register.
But then again. The therapist has to be working or nothing will ever be felt and one is left wondering what the hell is all about, because there's no 'felt' factor.
