Pain a dear friend

I heard that one who never leaves you is your friend
If it’s so my best friend shall be pain
Form the day I was born to what I’ve become
Pain is with be but other things have come and gone
Everybody left me never did pain
I’ve always been alone; pain has always been my friend
When I had fun, I had lots of people in my sight
But when I was in need of someone, everybody left in just a night
Even when everyone left me, as I didn’t had anything
Pain was always with me every time, pain is what makes me write and sing
They loved the one with everything, fun, joy, money, that’s the trend
If you don’t have that, you have pain a dear friend
