Letter Poem #4~ Tierney

How can I say it and not have it sound cliche? 
You'll never know what you mean to me babe, 
There is a reason we met, we are true sisters 
Together we will face and overcome great stricture 

Best friends for a whole seventeen 
There's nothing that we've never seen
Been through a million bands
Pretending to be number 1 fans

We've gone through lip syncing,
And years of singing
Milk out the nose, 
And oh how that blows. 

 We've been through the best and worst 
And times we thought we were cursed
With bad luck, disappointments, and broken dreams 
Our tears flowed together into perfect streams 

You're the reason I didn't move across the world 
Or run myself away when bad things swirled 
We have a million inside jokes 
And could easily pull off a hoax 

We have pictures of us in diapers 
Us in boas, and in costumes 
And soon enough the pictures will be heirlooms, 
Hung in our houses, treasured on wall in our favorite rooms 

We can think in perfect tune 
From March to June 
And I thank God everyday
That I have you 

You will always be my sister
And we will be best friends until the end 
So thank you pretty lady 
For being there when blue skies got shady

How can I say it and not have it sound cliche? 
You'll never know what you mean to me babe, 
There is a reason we met, we are true sisters 
Together we will face and overcome great stricture
