FOO issues definitely played a huge role in my low self-esteem, unworthiness, mistrust, etc. The A was a self-destructive act but it could just as easily have been alcholol or drugs. I find the language of addiction a handy way to describe the feelings I got out of the A.
That I've identified my FOO issues through IC is not nearly enough. I put my finger on these issues years before and swept them under the rug, not dealing with them honestly. I've got to learn constructive ways to deal with my pain and insecurities so I don't have another A or do anything else destructive ever again.
My ADHD compounds my problems and complicates my recovery, but none of the above is a valid excuse to do what I did.
