Musings About Love

Emotions confuse me. 
They change so rapidly
They knock the breath 
From your body. 
They catch you unawares, 
Taking your trust away from you 
And replacing it with distress. 
And love is the most complicated 
Of all feelings. 
You look at a friend 
Or a stranger 
And your world tips, 
Shifts, 
And suddenly you are filled 
With happiness 
And pain,
Joy and sorrow, 
Contentment and anxiety. 
Why do we always try to hide 
From the one we love, 
Though we often announce it 
To the rest of the world? 
What is the purpose of writing 
A love letter or poem to 
Your crush,  
If they're not going 
To recieve it?
