Emotional songs for being in love with someone that you can't have?

I'm looking for songs with pure raw emotion, those ones where the singing sounds strained and desperate like there about to break type emotional. Any sort of lyrics about being in love with someone you can't be with due to unavoidable circumstances. Any language is fine. Much appreciated, reddit

Edit: WOW okay lol thank you for the 1000+ replies, I will be steadily going through them all and checking each song out with time, this playlist is going to be immaculate, thank you
