I have read the book "Reinventing Your Life" (an introductory guide to schema theory) and taken the tests in it. The schemas I apparently have make sense to me. I am beginning to see evidence of them at work in my daily life.

I do not recall growing up in an abusive environment. My early years as I remember them were good. I believe schemas and the avoid/submit/overcompensate responses to them can be generated at ANY age, from different chronic or situational stressors; it's just that the earlier life schemas are more powerful and obvious. I also believe that schemas can interact with one another in ways that are not immediately apparent.
