I dont understand

You wouldnt know what its like to be alone
To feel so absolutely isolated
So utterly helpless
None of this is my fault
I dont understand
What am I have supposed to have done?
Do you even know?
You four sit to my left
Giggling, sharing secrets
But what about me?
I just dont understand
I did nothing wrong
Its not fair
Why is it always me
Always the one
Left behind
With not a friend
In the world
That gives a damn about me
I dont understand
