I know what you mean LNM, I would love a big clan about me, as it is we are transplanted all over the place, don't have close relationships with any blood members, I am totally single parenting my two.
I fought my position for many months and years, having expectations that were rarely met, being disappointed, frustrated, angry.
Gradually I surrendered and got some acceptance around the situation and started to build myself to be the parent they need.
I am very lucky to have made some fantastic friends, and have found the best way for me is to lead a somewhat spiritual life, churchgoing, meditation, affirmations etc. get me through moment to moment.
If you are seeking, I recommend eckhart tolle.
I am actually in the extraordinary position of being grateful for the crap thrown at me, because I love the life I have today!
Many of us through the other side will testify to that.
The death of the old life gives birth to a new one.
