I don't have a secure attachment style. And I agree with @comrademoomoo that normal can be identified. My childhood wasn't normal. Too many adverse childhood experiences (ACE's). My parents did try but some things were beyond their control and I learned early on that it wasn't safe to trust grown ups. (Even my parents.) Even though now as an adult I have a good relationship with them. But the damage is done. I don't know if I can undo it.
