All about love

You did missed me,
So did I.
You said you want to sleep.
I said I want to die.
You said to me that you don't care,
I said I'll cut my arms to bleed.
You said "Good luck with that boy, huh".
I cried spelling "Love you, do admit".
Now you're saying want me back.
But I'm buried under ground
When I've heard that words -
"Good luck".
