Fighting for what?

Throw it all at me
i don’t care no more
There’s nothing left to fight for
all my strength has gone
my voice is just a croak 
I was once so strong
now I’m weak

I spent so many months fighting
i still don’t know what for
Now the battle
is getting up off the floor
things that were so easy
i now battle against
sleep is no longer my friend

I'm exhausted 
days are blending into one
I’m so confused 
i struggle to add one

the strong front I used to put up 
has fallen
leaving behind what was hiding 
someone trying so hard
and inside is dying
