We've been estranged from our youngest son for 7 years and have two GC we cannot see. The eldest who will be 8 next year, we haven't seen since 8 months of age, and the youngest we've never seen.
Yennifer you cannot hold onto something that isn't there, I know I tried. Please try to let it go, that's hard to do but you cannot spend your life worrying about something and making yourself ill over something you cannot change.
We didn't emigrate but we moved away, not that great a distance actually but enough to begin a new chapter in our lives. Enough so we wouldn't risk seeing our son and GC which we often did as they lived only 15 doors away from us.
I don't know what it's like to have a mother who didn't love and care for you the way she should have, and the way you deserved, but I do know what the pain of estrangement is like.
Live your life Yennifer, don't waste it on someone who didn't realise how lucky she was to have you for a D and threw you away.
