I know how completely alone you feel. Your brain is most likely swollen...micro-encephalitis.
Could you take some Ibuprofen??? for swelling of brain or NSAIDS (non-steroidal anti-inflammatories)??Hot baths w/ epsom salts and botle of h2o2(not to drink, to put in tub). Soak for 30-40 min.
Dink several teaspoons (mega doses get the gall bladder & liver to start pushing out toxins) of buffered vitamin C in water (from health food store) throughout the day. Make sure you are getting Magnesium/calcium as well. Very important!!!
Crying really helps reduce the pressure in the head for some unknown reason. Probably releases tension, which allows blood flow to brain and allows brain to feel better. Some chemicals such as endorphins are also release d most likely....feel-good chemicals in brain. Body is seeking to rebalance itself.
Toxins come out through tears as well. There are lots of reasons why crying is GOOD for you when you herx!!!!
I used to be a runner and competitive swimmer before I got lymed....that was my stress release valve...never had to cry, the exercise oxygenated brain and produced natural endorphins. Now that we cannot do aerobic exercise w/o feeling like crud the next day, crying is a release valve.
IF you are herxing, this would make sense...
Have you recently started new meds???
Is it the 4 week flare-up???
Keep a calendar if you don't already: an X for bad day (like you described), a really dark X for the worst days, a - sign for bad day but a little better than X day, and a 0 for a "good" day relative to bad days.....
Hang in there! This is soooo rough....If you need to go out to the car to cry...that is what I have found does not freak out the family. bring a pillow and a good CD that speaks to your heart and blubber away. No one can hear you and you can get it out!!! 
For more on crying therapy you can e-mail me offline! 
saying a little prayer for you!
