I can understand that you might not feel ready to share your story yet Starblaze; it took me a long, long time before I felt ready to. Like you, I also felt that, as most of the other contributors to the estrangement threads were the parents of estranged adult children, that I would receive a somewhat frosty reception. In fact I was welcomed immediately and I became more comfortable in explaining estrangement "from the other perspective". I've never given the actual reasons as to why I walked away from my birth family, but I've been quite open that it's been a decision that I had to take for my own sanity and wellbeing and is something that I've never regretted.
We all have our own journey to make, whichever side of estrangement we're coming from. I do hope you keep posting. Best wishes.
