I accept your feedback and appreciate your input Boat. I have not been consciously trying to get as back for anything and not trying to control her at all.
Will bring this scenario and these ideas up in therapy.
I think that I was maxed out at the time and erroneously thought since it wasn’t a 911 kind of crisis, I would not interrupt or worry W or put myself through the added stress of contacting her.
I actually told my sister that morning. If anything gets serious please notify W. With reflection and from W telling me she was hurt, I see that this event crossed a threshold where Mom needs to know and that I should get that done.
