why am i afraid of rainy days?

Why on earth would i be afraid of rainy days?
  well it's not really the rain itself that i am afraid of...
I'm afraid of the power rain has-
   how it can transform a bright, hot, sunny day 
   into a dark, cold, gloomy night in an instant. 
Rain turns blossoming trees into a pile of leaves. 
It turns newly rich soil into a muddy mess. 
It turns a white cotton-ball like cloud into a dying grey blob.
Some people protest, "but rain brings life!" 
   and i respond, "but so does the sun..." 
I'm afraid of a new happy day turned into a sad blur 
   all because of little watery tears falling from the sky. 
No matter what you say...
   i'll always be afraid of rainy days.
