A losing battle/ a neverending war

I'm in a losing battle,
a nevereding war,
a strugle to survive,
yet the hardest part,
the bravest enemy,
the one who could tear me apart,
rip me into shreds,
break me into peices,
the one I fear most,
is the one who I cant controal,
there are screams,
over and over again,
but they are never to be heard,
for it is a weekness,
a disadvantage, a thret,
the sadness I have felt
shall never be revieled,
for my enemy will prevail,
I am fighting a losing battle,
a neverending war,
problem is
how do you defete yourself?
