Fix a Heart

It is a pop piano ballad that Lovato and some critics described as a break-up song, while other authors noted references in the lyrics about the singer's issues with self-harm.

[2][3][4] In June 2011, website Disney Info Net published the songwriting discography of Priscilla Renea, which included the titles of two then-unreleased songs recorded by Lovato, "Fix a Heart" and "Yes I Am".

[10] Jenny Chen of Neon Tommy wrote that Lovato "openly admits her weaknesses, including an ability to move on from a broken heart left behind by a former love".

[17] Other publications, such as PopMatters, BlogCritics, and Entertainment Weekly, suggested that the track referenced Lovato's previous problems with self-harm,[18] specifically in the lines "I try to sever ties and I/ Ended up with wounds to bind/ Like you're pouring salt in my cuts/ And I just ran out of band-aids".

[21] Jason Scott of Blogcritics called it a "gem" and wrote that "Lovato's pain runs so deep that this soul-baring song feels like a punch in the gut".

[19] Both Sputnikmusic's Raul Stanciu and Rick Florino of Artistdirect considered it a stand-out track of Unbroken,[11][15] while Ed Masley of The Arizona Republic ranked it at number 28 on his list of the best songs of 2011, writing, "It's a moody waltz-time ballad whose cello-driven sense of atmosphere places it closer to something Coldplay might have done, although the phrasing makes it sound like she's been getting into '60s soul, her vocal cracking just enough to say, 'I'm feeling this'.

[10] AllMusic's Stephen Thomas Erlewine selected the track as an album pick, but stated that the honest songs on Unbroken, including "Fix a Heart", "Skyscraper" and "For the Love of a Daughter", were similar to the content of Lindsay Lohan's record A Little More Personal (Raw) (2005).

[16] Laurence Green of musicOMH said, "'Fix a Heart' and 'Skyscraper' achieve the maturity the album's opening moments were crying out for – trembling, beautiful creations built on sweeping, rhapsodic interplays of piano chords and strings".

[29][31] A recording of Lovato's tour performance at the Hershey Theatre on November 19, 2011 was released onto the iTunes on January 1, 2012 and was later included on the deluxe edition of Unbroken.

[36] Music Connection Magazine noted that the recording and "Skyscraper" were the oldest songs on the set list, and expressed disappointment over the omission of tracks from the singer's earlier material.

[37] It was performed as part of an acoustic medley with "Nightingale" and "Warrior";[37][38][39] the singer starts singing accompanied by a guitarist, while the others members of the backing band join them towards the end.

[41] Kelli Skye Fadroski of Daily Breeze gave a positive review of the concert held at the Honda Center in Anaheim, California, saying, "Slowing things a bit [after singing 'Body Say'], she pulled a bar stool onto the catwalk and absolutely killed during 'Fix a Heart'".
