Out of curiosity this morning, I Googled "parents estranged from children" and found several other Websites on the painful subject. At GardenWeb.com (of all places!), I found a page–Mothers estranged from adult children–on the Parents Forum, where many mothers post their heartaches. From this page, I found Estranged Stories, a members-only site that must have more than 800 members. The site, which is very sophisticated, offers forums, blogs, videos, groups and chat. Since I'm not a member, I can't further describe what's there.
I also found Healing Estranged Relationships, which is based in Dallas. Estranged Parents of Adult Children is a very simple website, which also has a lengthy list of book resources. And there's an active forum at DailyStrength Groups-Parents of Estranged Adult Children Everywhere.
What all these websites together say is that: THERE ARE MANY, MANY BROKEN BONDS IN OUR SOCIETY. You are not alone!!
Beyond prayers, I wish we could provide much more through this blog. Because we can't, I will point you toward these other sites, where you may find more of the help you really need.
God bless you.
