I live in Australia. For five-and-a-half years I was in the worst relationship of my life with a person I would later learn, from various sources including specialists, was a borderline/narcissistic personality. By the end of it my sense of self had been almost completely destroyed, I had no confidence, everything had become a kind of relativistic miasma, my self-esteem was shot, I couldn't think about the future and barely had the energy to get through the day.
