I am sorry I cannot offer more than what has been written already above, and to make sure that you DO get straight onto centrelink and organise yourself on that front, in touch with a counsellor or with a gp to get you onto a mental health plan (discounted counselling), and also make sure you eat properly, even if your are not hungry.

All the ladies on here, me included, are right behind you and your children, wishing you strength and a clear way forward.
