Maybe Tomorrow

Does anybody really know
When it's time to let go?
Is it when the pain is too much?
But how does one know when it's such?

Silly me for asking this
But what if the pain goes away with just one kiss?
When once again the grip is tight
You tend to hold on with all your might.

Most of your friends say you need to wake up
But what the hell, they don't know what's up.
You make yourself believe everything is getting better
Even when deep inside you're crumbling altogether.

So how does one know when it's time to let go?
Does it always end with 'maybe tomorrow'?
