In analyzing my fears of abandonment regarding BPD, I've found some interesting similarities between our fate and the fate of Macbeth.
In Shakespears play Macbeth, the three Witches give Macbeth a prophecy that he will eventually become king, but the offspring of his best friend will rule after him. Macbeth kills his king and his friend Banquo. In addition to these prophecies, other prophecies foretelling his downfall are given, such as that he will not be attacked until a forest moves to his castle, and that no man ever born of a woman can kill him. In the end, fate is what drives the House of Macbeth mad and ultimately kills them, as Macbeth is killed by a man who was never 'born' as the man was torn from his mother's womb by caesarean section.
Macbeth caused his own propehcies to come true by trying to avoid them. For me it feels like my BPD(the personification of) once prophesied that I would end up being abandoned by everyone(imagined abandonment), be alone, and eventually die alone. So in my efforts to prevent that from happening, I tragically push everyone away. As I understand that, it is common among those with BPD to push those they care about away in their effort to keep everyone from leaving them, not because they want to push them away, but because this happens as result of avoiding this abandonment. Intially this fear is imagined, later as we struggle to avoid that fear and push everyone away, this fear becomes real, which validates our original fear, and we risk being alone.
