Dear,

Dear  NAME, I'm incredibly sorry that you have to be reading this. I know that it's selfish, but I've been  ADVERB suffering for a while. I don't mean to burden you. This is the last thing you need.  EXCLAMTION, you don't know how hard this was for me. I've been thinking about doing this for the last  NUMBER days, and i've had enough. with  NOUN,
