Erase you with an eraser

I was curious about how to overcome a break up

So I searched for the method online
Then I found something that I could relate to
It said that I should hurt as long as I needed to hurt

Just one day, just one day, can’t I hurt for one day only?
Because that one day will be like hell to me
Just like those lovers who easily forget and love again
I want to be like that too
