Painting words

Good comes to those who wait?
I've waited a thousand years.
I've been waiting and I think it's getting late,
As I'm running out of tears.

I did everything I could,
To make you stay by my side,
If my heart is wood,
Your name's woodpecker only pecks it wide.

Trying to stay strong,
It's not as easy as it looks.
I know because I've been trying for way too long.
With what I feel I could write a million books.

Yet I wish that you shall never be sad,
Yet I wish you shan't cry,
Your son could have been my lad,
This, I'll regret until I die.
