I have friends!

I have friends!
The best in the world!
They talk to me and tell me,
All their little lies,
Exaggerate their stories,
About their brilliant lives,
They talk to others about me,
And tell their little lies,
Exaggerate their stories,
About my sordid life,
They make me keep secrets,
And share all of mine,
They use me for my kindness,
But they never have the time,
To help me when I need it most,
But then that’s not a crime,
I make excuses for them,
Why they treat me this way,
So could someone please tell me?
Why do I have friends?
