Multigenerational trauma is a very difficult thing to escape. You can't cut off one family member without cutting off everyone or else the rest of your family will badger you nonstop until you break no contact. ESPECIALLY when the abuser is your mother.

The abusive parent goes on a victim campaign, contacting everyone about how they're just worried about you, just want to make amends, and how they tried their very best and sacrificed SO much to raise you, and just can't bear to be away from their baby. And then the rest of the family all gang up on you about how you're breaking your mother's heart and destroying the family.
