I would finish early. That kind of stress is the last thing you need!!

I would head off to your GP and ask that you have a week's stress leave - in which case your work will have to pay you sick leave for that week (provided you have enough accrued). That way it won't be LWOP.

You've given them your all and they are kicking you down as a final send off. Beat them at their own game and get your doctor to give you leave!
