I'm so sorry you are having such a bad, bad day. :(
Some herbs help the kidneys. Alfalfa helps promote kidney function, and Burdock Root is a cleansing agent. I wonder if these things would help you at all? I know when I am in need of a diuretic, I take Uva Ursi and it works like a charm. Not sure you need that right now.
Maybe what you need is 1) some yummy chocolate, 2) some warm and comforting hugs and 3) for this problem to pass straight away. Here's wishing all three things your way -- take care of you! {{{{hugs}}}}
