The sandwich generation - BPD family version

[Freereveryday]

After my daughter (27) was finally diagnosed this last January my mother's behavior throughout my childhood and her life finally made sense.. I've done a lot to process the very deep wounds I had previously thought were healed after my daughter displayed cruel, rageful and hateful behavior towards her almost 2 year old daughter while they were staying with me for an extended period of time.
The day she venomently defended screaming at her child, rageful, threatening and filled with profanities to hold still for a diaper change right after waking up I swear that a younger version of my mother rose from the dead.
Reliving that nightmare was torture compounded by it reoccurring to my granddaughter and my total inability to stop it.
It was a long, chaotic ordeal. I was able to care for my granddaughter away from her mom for a period of time but had to return her to her care. I've done everything I can to get help for the child.
My daughter went NC as soon as her daughter was returned. It's not clear exactly why. I hope it's because someone intervened. I'm not good at deciphering her thought processes so I try not to spend time speculating.
My heart is heavy for that sweet, empathic little girl living through intentionally inflicted emotional pain and the destabilizing confusion that fills her home.
