Jan, I worked in a shelter for a while - it was here in the UK, but they might very well bite your hand off should you offer to run workshops for the other ladies there.
Whatever you do, always believe that you *are* sane, you're doing the right thing. Where I grew up (northern Germany, sea-faring nation and all that), there was a dialect saying 'hol di fuchtig'. It kind of means 'hold on tight, stand up straight, look the future in the eye, keep fighting'.
Hol di fuchtig, Jan - thinking of you.
