(Giertrude) As pen says, keep and value your friends but on the other hand don't pretend nothing has changed. You may find yourself more at home with one or two new people. My mother was widowed for 27 years and had to find a few new activities and friends which she did successfully. We can all do it and I wish you all strength.
Sincere condolences on the loss of your mother. It is surprising how much we do either for, or because of, or by reference to our mothers and the loss of that key reference point throws our lives off balance for a while. You will recover that equilibrium over time. Until then, focus on what is necessary for you and for those you love, take comfort from the familiar (Glow-worms!) and try not to dwell on the loss.
We haven't had a general poetry game for a while. At the moment there's just Wretchedly Difficult Poetry and Slightly Less Wretchedly Difficult Poetry, both at Orange, taking about a year per poem. Shall I compare us to a plate of eels?
