It sounds like he is just trying to wear you down and confuse you. Turn down the volume or get out of the front row or whatever metaphor you need to help you back off from all this quacking and focus on what makes you happy, moment by moment, day by day.
I know how confusing and overwhelming all of this can be but you have more power here than you give yourself credit for. Sending strength and courage and patience your way.
