Beetle Bailey, I can relate with your writing. But I disagree with your statement that we can't control our brains.

Our brains are not static. If they were we would be incapable of learning anything. However we are capable of learning, precisely because our brains are not static.
In this thread we have focused on different brain hemispheres and how they function.
If our left brain is capable of learning, then is not our right brain also capable of change.
It is my belief that right brain traumatic memories, to some extent, can be disrupted. Not through force of will, but by actually putting the right brain to work.
