Control - to what extent?

On the street and a km away from home, the urinary bladder is full till the tip.
Too sick and physically unfit to drive the car on own or take an auto.
The purse is empty ruling out the option of calling a city taxi. Need to walk half a km out of the way to fill the purse.
Every small step I put forward makes me want to pee the next moment.
Desparately looking into the passing cars for a known face.

Clouds of self-pity, depression and the cold night makes it feel more worse.

Every passing second seems to be an eternity. Alas, got to hit the toilet after all this. Never have been a more relieving moment than when the bladder was emptied...
