Post-modern psycho babble in a nut shell. This loser has "struggled her whole life" until she seeks therapy. The therapist helps her "uncover" deep secrets from her past which may not have even taken place (she even admits they may not have taken place). Next step: Get on the horn and tell your Mom that your Dad molested you as a child. Sounds like an old ATT commercial, doesn't it?
So now her Mom is the bad guy for not cleaning up the pile of crap that Heche just dumped on her doorstep after "she had gone through so much work to heal."
The pop culture religion of the Post-Modern world is that self and experience equate to God. So in this loser's twisted world, her mother was a bit player who was expected to play her part and help her be "healed" of an event she's not even sure occurred.
To quote my favorite movie, Miller's Crossing, she's one sick twist.
Isn't that always the easy way out for some of these folks. Excuses, excuses.
