a song conveying the pain of romantic love

If you think my posts have been going downhill recently, they’re about to take another nose-dive. I’ve never done a song post before, but this song is ringing round my head and I’d like to share it in other people’s heads.  Lianne La Havas is probably my favourite current singer, an amazing musician with a stunning voice. This song reminds me the pain of breaking up, the irrational pain of romantic love that we find so hard to separate from the chemicals causing it.
