A sense of doubt

Have you ever felt so tired?
Have you even less than required?
The feeling of so uninspired?
It's been too long now

When your lungs start gasping for air
When you came so far but never got there
When you held back so long and it's too much to bear
Is it too late?

You can't stand the thought of being without
Yet you can't help to feel a sense of doubt
When noone can hear you even if you shout
Has the light gone out?

When your lungs start gasping for air
When you came so far but never got there
When you held back so long and it's too much to bear
Is it too late?

It's been too long now
Has the light gone out?
Without you I'm nothing
I'm without you too often
I just need you to write something down for me
