Loneliness is painful. It's even more painful when you're lonely in a crowd.
Buttercup, you are the mother of four teenagers. That must take a lot out of you (
understatement!). On top of that, you've been through some terrible (
another understatement) stuff. I'm impressed you are where you are.
I wish I had some real anti-loneliness advice to give or techniques to share; I don't -- I'm pretty much a recluse.
Please hug your Westie for me.
