Sylvia, I've been wondering for a while about the same person (guessing here, but I'm sure I'm right).
I haven't even seen her online for ages, I do hope she's all right.
Margaret, people post here when they feel the need for support, or want some company. It's up to each of us how much we post, and if we want to take a break, that's up to us. Though of course we all worry if we know the person was in distress. But we are all anonymous, as we should be, so there's little anyone can do, apart from welcome them back, if they choose to post again.
