At a loss for what to do as our almost 19year old daughter just wants to blame us
How do you respond when she blames you?
Maybe we can walk with you and try to troubleshoot different ways to respond that we've tried.
It's likely she sees that blaming you increases your guilt and gets you to back off a bit. I like the sentiment of acceptance and change: we did the best could and we can always do better. It helps with guilt so you can move forward and not get stuck there.
Acceptance and change are not always friendly neighbors in our minds
