Strength is gone

I have always tried so hard
to get to where i want to be
but when all my strength is gone
They look at me as if I'm crazy
I've worked for everything I've ever had
The one time i ask for help;
i get nothing, all my strength is gone
but they don't believe me
they tell me to go on

I feel almost like I'm drowning
and I'm screaming for help
but they just yell
" you can do it! You've swam before!"

even people who know how to swim sometimes drown
and even thoughs who know how to fight
sometimes need a hand
sometimes the world just gets so heavy
and the walls begin to close in
i am not strong enough now
to keep thoughs walls from killing me
why wont someone help me?
