Ah, my utter commiserations. There's no advice I can give other than "please try to find a good divorce lawyer". If that bit can even be considered advice.

It can be hard to carry on in such a depressive atmosphere, but the best thing that can give a mind some rest is planning -- plan for everything meticulously and in written form,try to plan for the very worst situations first. Again, seems like common sense advice to some, but if you're not used to doing this for non-work related activities it could be surprising how much this actually helps.
