You Don't Know The Pain I Have

You don't know the pain you caused me to have
You don't know the sadness I feel or the pain I have to live with
You don't know the sadness I feel
I lie awake at night wondering if we could've been
But I always think no like you said
Maybe someday we will meet again
Maybe this time will be better than the first
For now I just wonder why I have pain, hurt, and sadness
When we meet again I hope it's pleasant
You don't know the pain I have
