I wanted to post this list from the book Adult Children of Alcoholics...you can also be the adult child of a dysfuntional parent who didn't drink and may have some of these same traits. I have some of them, and my husband has some of them.
Adult Children of Alcoholics:
~guess at what normal behavior is
~have difficulty following a project through from beginning to end
~lie when it would be just as easy to tell the truth
~judge themselves without mercy
~have difficulty having fun
~take themselves very seriously
~have difficulty with intimate relationships
~over-react to changes over which they have no control
~constantly seek approval and affirmation
~usually feel that they are different from other people
~are usually super responsible, or super irresponsible
~are extremely loyal, even in the face of evidence that the loyalty is undeserved
~are impulsive; they tend to lock themselves into a course of action without giving serious consideration to alternative behaviors or possible consequences.
