This is probably going to be more than 15 lines but...here goes nothing
As I lay on my sunken bed 
  I hear his voice inside my head 
Thinking I should have stayed 
This tune I hear repeating in my head 
I can’t go back, come here instead 
He’s not here, he’s gone back home 
The love he’d shown was not for me. And I moved on 
My sister was jealous, telling me lies
I knew something was going on , it brought tears to my eyes
As I lay on my sunken bed 
 —-finish the rest I know it sounds soo bad. ♀️ sorry I tried though
