Our illness, depression, feeds us lies we believe to be true. Sometimes the only way to release all those negative emotions is to cry. Unfortunately we don't get to schedule "tear events", they just happen.

In the checkout line of Walmart (replenishing my Kleenex supply)
While eating in a crowded restaurant
Even while filling my car at the gas station (of course those tears may have been caused by the price per gallon rather than depression)

I'm hoping your tear sessions end quickly or at least play by the "not while in public" rule.
