Reset on the meta level.
It is clearly possible to hot swap the knowledge. See whatever the mind is saying is based on the previous experiences and how I interpreted them the net result is my mind is saying few things, I can choose to put my faith in it or I can choose to take my attention away from it. Even in the full noise of it I can continue working, I can also hot replace the beliefs.
There certain things which are only problematic. like a self judgement. there certain things which are beautiful I know this based on feeling.
So thing I need to do at this point is to create a new structure and belief and act according to it, make this based on the fact, experience and understanding. and then practice. it is not about yours and others but weather it is true and factual or not.
