What doesn't kill you make you stronger

What tore you to pieces. What made you cry yourself to sleep.
What kept you astray and distracted.
What messes with your head.
What comes and goes painfully as they like.
What trips your appetite.
What taught you to stand tall after falling.
What made you learn life lessons better.
What made you appreciate the people around you.
What built a stronger you.
What unearthed the underlying values.
What now made you stronger, better, awesomer.
