The Trouble with Ally

Ally doesn't particularly want to turn fifty – but it doesn't bother her half as much as everything else in her life is bothering her right now. Still smarting from the fact that her husband left her for a younger woman, she's trying to cope single-handedly with a sick elderly cat, a sick elderly mother and a sick elderly car – to say nothing of two daughters who treat the house much like a comfortable hotel. And on top of everything else, she's having trouble hanging on to her job.
So why does everyone else seem to think turning fifty is the trouble? And why does everyone seem to think she's losing her mind? She's not really going crazy ... or is she?
