That seems hugely significant. Suggests to me that maybe she was not properly attuned to you and so you had to tune in to her needs as a coping strategy and survival style in early life.

In attachment theory they identify a few different "insecure" attachment styles, but i find that they overlap somewhat confusingly, and the main concept for me is secure vs insecure. With the former the child has a so called "secure base" and develops healthy sense of self, trust, and ability to self regulate. With insecure attachment the child internalizes shame, experiences the world as unsafe, does not trust, has trouble regulating emotions and physiology and so on. Thats just my rough interpretation...
