Are we ever understood?

Understanding,
We all yearn for an understanding,
Whether if to understand why the sky is blue,
Or the earth is round,
We all yearn for an understanding. 

We try to understand words with multiple meanings,
Letters written in different ways.
We try understanding english,
With all this no-need slang.

We yearn for an understanding,
Of ourselves and of those around us,
For the words they speak,
We hear differently.

Will we ever fill tha yearn for understanding?
Know why teenagers are more depressed,
More stressed,
Less dressed, 
Start from a caress?

Who knows why we call ourselves fat,
We call it ugly,
We call it hideous,
We call scary.

Who knows why we call ourselves useless,
We call it helpless,
We call it independence,
We call it needy.

How can we understand others,
If we can't understand oursleves?
We think we know,
But truly do we ever know?
