I have not managed to read through all of the replies to the original post, but I did read through the DM article.
My adopted DD is 14. She has been living with us for 10 and a half years. She suffered neglect and a catastrophic non-accidental injury at 22 months which has scarred her significantly for life. She has RAD - mostly as a result of the neglect before AND after her injury (hospitalised with no parent present for 3 months aged 2 post-injury). She probably did not suffer abuse and neglect for as long or as overtly as 'Alex' - the only surprise to me is that everyone is so surprised at Alex's brokenness. I spent the first 18-24 months of her placement positively willing my DD to be 'normal against all the odds'. When I had my first birth child I realised everything DD had not had and finally gave in and allowed her to be broken - to recognise and accept that no one can go through what she had been through and not be deeply and - I believe - pretty permanently damaged. It took DH another 18-24 months and 6 years ago we started to properly address the issues, including understanding how attachment disorders are not just about the child - our attachments are all disordered and yes, a lot of strange control stuff is part of that. We are all living in some kind of survival, self-preservation mode ALL THE TIME. It never ever ends. Self-awareness is the only things that begins to heal it or allow coping to a greater or lesser extent.
Nothing in this article surprises me, nor is exaggerated or overrated. Living with a child with RAD is unbelievably hard work. It is relentless. You live burned-out. You live emotionally damaged. You live with a reality that most people you know and nearly all people you meet will not ever understand what shape your life has become or what effort it takes to process all the stuff going on within your family every single day. That said, I believe we have 'got off lightly'. My daughter is clever and capable and academically able. She is bright and funny and loves us and her siblings immeasurably. She has attached well to us, but even after 10 years every single day is a challenge and a work in progress. She still struggles to trust. She copes with life by dissociative behaviour and can be hideous company. She will struggle with relationships her whole life, I believe. My whole body often hurts with the effort of loving and living with her.
AND we now have good, accessible, specialised support, though only because DD has been awarded specific criminal injuries compensation in order to afford it. Without that we would, frankly, be lost.
If you know someone who has adopted and you cannot make sense of what they are saying about their home life. Stop trying to understand, at least before you have properly found out about and understood RAD and it's affects. Once you have grasped the enormity and all pervading nature of it, you will understand what has happened to your friend or loved one. Then encourage them to seek specialised (probably private) therapeutic help. Then offer them unbelievable and unconditional acts of love and acceptance.
That is all.
