I am wondering if this is activating something from your past for you. I get very black and white like this when something in the present day is very upsetting and pushing up against old wounds. It's hard to imagine a scenario in which a therapist would spend five years working with somebody on what sounds like some pretty deep, intense stuff without taking the work seriously at all. I think this is the piece you'll have to hash out with him in more detail -- maybe more than once -- in order to resolve it.
