That's why I'm not even angry about my situation because it has been my own choices that brought me to this point.
If you watch very carefully, you might find that your mind carries a root belief of being fundamentally less than other people.
This self-image was created in childhood to explain why we have been treated more harshly than other people, be it scapegoating, bullying or other scenarios of being personally singled out for abuse. We may do this to eliminate
cognitive dissonance; we are clearly human like anyone else, so why have we experienced unjustifiable attacks? By affirming, "I'm worthless and unlovable (etc.)" we now have a fully self-consistent, resolved worldview. Never mind that it's bollocks.
Once the 'I'm inferior' seed is established, the mind will interpret all events in ways that bring us blame/shame, ignore the crimes of our abusers and are generally totally biased against ourselves. This can manifest substandard outcomes such as bad relationships, and becomes a vicious circle that continually reaffirms the sense of unworthiness. We become our own tormentor.
The situation strikes me as the polar opposite of narcissistic personality disorder, a condition that can make people believe in their own superiority to the extent that they feel completely entitled to brutalise and manipulate people around them. If you've ever experienced narcissistic abuse, well it's a case of 'join the dots' to see what's happened.
