Stab me with your heartbound knife and burn me inside
Take the ashes of my life and throw them aside

I need help revising this line. I like the first part with the stab me with a heartbound knife thing and I want the next part to be something about burning me and then taking my ashes and throwing them away like they dont care but the words ive chosen so far are a little bland and I cant think of anything really. Please help (dont rewrite the entire line just help me revise it thanks).
