You just look pathetic now

You didn't feel too well that day at school, so with permission from your teacher, you went to the infirmary, where the school nurse informed you that you were "entering a new phase of your life" ...

Here you were thinking it was just you "hitting puberty", and feeling a little nauseous, but it was getting worse, so the nurse decided to call your mother and send you home.
When your mom got to the infirmary, the nurse pulled her aside, and talked quietly for what seemed to be an hour. Your mother didn't seem too bothered however, and a little after, the principal walked in. Probably to have your mom sign some legal paper to say you were leaving school for the day.

You hopped in the car, and pretty rapidly fell asleep. The drugs the nurse gave you were pretty strong and sure helped in knocking you out cold, to get some needed rest.

As you were waking up however, the world around you seemed to have changed ... to have wildly grown.

And right there, towering above you, was your mother, looking down with a disappointed look on her face.
"Well, I knew having a boy could result in this, ever since the pandemic, I'd been warned ... but here we are now, I took the chance, and look at what you've become" she said. 

You didn't quite understand, but she then proceeded to explain a little more to you, telling you that the pandemic had caused worldwide genetic corruption of the male DNA which had a 60% chance of leading to shrinkage when the child hit puberty, causing his hormones to make him shrink to only a couple inches tall.

"Both the nurse and your principal said the best course of action was to just dispose of you, instead of living in fear of what could happen to you by accident.
So, since I bought you into this world, I think I should be the one to kill you and end your suffering. Love you"

And with those words, and no second thought, she lifted her foot above you, and with her heel, slammed down onto your tiny body.
As your bones broke, and you began to bleed she lifted her foot to stomp down again, your vision had become blurry from the concussive force, but you could see the blood stain on the bottom of her foot, and looking back to her face, saw a look of disdain as she was slightly grossed out.
Then she stomped back down a couple times and began grinding her heel, and you into a mere lump of pulverized flesh and bone, that once used to be her son.
