thismoment,
unfortunately when i clicked on the link i got the following message:

i understand what you mean about changed brains - however, we make choices that make that change, it may be in order to what we think requires our survival. but it is always a choice. there are no shoulds or musts. just things that may be (or may not be) in our best interest. once we choose to think something, then neuroplasticity comes into play to hardwire that connection. that's why anxiety is such a bitch.
