I’ve been thinking about JM (unfortunately not much else to do on furlough).
I don’t think she is really a recovering alcoholic. If you do the work involved with the steps you are told what your character defects are. And then by working the steps you take action to “sort them out”. The steps are ongoing.
IMO one of Jacks problems is the resentment she feels towards the foster children looked after in her home. Also IMO she felt/feels neglected. She may have other problems in addition.
I think her resentments have resulted in a huge sense of entitlement. She thinks she is a special case.
I think she gets away with all her scams because she believes she is hard done by (going back to her childhood. That belief makes it easy for her to lie because she is living in her own version of reality.
