Best wishes, Razz! I found your posts helpful and informative, comforting. Hopefully folks like you that seek boards for help and encouragement will not feel so displaced in the future. Estrangement is a very biased topic to begin with, and camps on either side are somewhat vigilant to their cause, IMO. You may find better acceptance on searching for 'adult children of estranged parents' where the support is more aligned to those that have suffered abuse from our parents.
Fortunately, there many, many studies being done on support groups, forums and blogs that bring to light the topics and divisions, and I'm hopeful that in the future much of the barriers between GPs and ACs may diminish from knowledge the knowledge gained therein.
One such study is here (there are many others), that you may find helpful:
