Can't win

Depression comes to me all the time,
in my dreams it appears as a beast,
chasing me until i cannot run anymore,
last night it caught me, pulled me to the floor,
and beat me so bad and threw me in the river filled with lost hopes and dreams,
so i am struggling to stay alive, keeping my head above water,
but in this battle i cannot win, evil with prevail,
so i must stop fighting it, and let my soul sail...

*i don't really know where i was going with this poem but it is based upon a dream i had, vote and comment please, and i will do the same for yours*
