Susan,
I'm so sorry you were low. Glad to hear you are getting better.
It hurts to be ignored and then that inturn can chip away at one's self worth...... which, I believe.... can result into isolating as one doesn't feel they matter enough to be cared about. And also, I think it can make one feel safer as it's hard to be hurt further if one is isolating.
I do this also.... hide when I'm so low.
Good to hear that you have regained some of your emotional strength-- and good to "see" you around!
(Oh, I have a new name and siggy! mandy)
