Attempt at Wording Joy

I must write of you
I must capture every image
I must imprint every word
I must pull chaos from order
From what I had deemed absurd

I must write of you
But I only meet shortcomings
As I tear through books of lines
Barely glimpsing the idea
Of what it means to call you mine

I must write of you
But poetry is for the solemn
And sadness makes its home in prose
When I have joy, it's treasured deeply
Why should I write and let it go
