They make you feel worthless with jabs, insults, by ignoring you, minimizing your pain. When you finally have emotions like anger, sadness, loneliness or fear that's when they start cutting you off making you question whether or not your feeling are right, making you feel even more worthless. When you're at your lowest they're satisfied. What's really hard is everyone around them takes their side. It's not that surprising their are bad people in the world. I expect that. It's surprising that I can't find any good ones.
