Hi
I think you need to think what is it you would like yourself as one of such women - would this be a meeting with few other strangers all winging and crying while looking what clothes others are wearing and chewing on cakes
or, perhaps, phone in - sort of helpline with number where one could call when feeling blue, or in need of support? ... as we often can at odd times of a day..
... later you could think about some convenient space, could be local coffee shop at back table, where to meet for more cheerful and energising optimistic chat?
You cold try to persuade to go on short walks together, to get some fresh air and exercise too, or organise to go to see something interesting together... I don't think you really need any 'office' for all that.
I think ladies here could help to think, by letting their fantasy work to imagine this what is it they are, themselves, are missing most in the whole stress on Meno?
Let me guess... a warm hug?.. a bit of attention? ... someones' concern? ... practical advice...? ... holding hand?
Would you bother with regular meetings or prefer just to know that there is some person and space you could go to if you felt worried or confused? ...
