The album lyrically revolves around themes of mental health, grief and heartbreak, as well as Beer's experiences with public scrutiny and building resilience during the making of the record.

[9][10] In an interview with Zach Sang and Dan Zolot, Beer confirmed that she was inspired by a variety of artists, including Tame Impala, Lana Del Rey, Ariana Grande and Twenty One Pilots.

[6] "Good in Goodbye" is a break-up anthem[12] with a dark melody[13] that, according to Beer, is about "cutting ties with a toxic person, no matter how tough it can feel at the time, is sometimes the only way forward."

[18][16] "Sour Times" was inspired by Tame Impala, with lyrics detailing Beer's experiences with harassment and getting taken advantage due to a mentally vulnerable state.

The country ballad "Homesick" samples a dialogue of the sci-fi animated sitcom Rick and Morty, which Madison states is her favorite cartoon.

Primarily, the songs talks about social alienation and Beer's abandonment issues, by referencing her beliefs in outer space species.

[14] It reached number 15 on the New Zealand Hot Singles chart and impacted contemporary hit radio in Italy on April 3, 2020.

The American leg of the tour began on October 18, 2021, in Toronto at Queen Elizabeth Theatre and ended on November 28, 2021, in Los Angeles at The Wiltern.

[25] Life Support was met with positive reviews from critics upon its release, many of whom praised her vocal performance and the album's subject matter.

[33] Writing for Beats Per Minute, JT Early said: "Life Support is a lovingly-crafted project which explores mental health, heartbreak, toxicity and self-assertion.

The soundscapes here are cinematic and cohesive, while Beer's versatile vocals easily go from sultry to dreamily resonant to emphatically cold.

"[29] Hannah Mylrea of NME wrote: "On a lesser album, the eclecticism might lead to a lack of coherence, but this record is always threaded through with Beer's diaristic lyricism.

"[30] Marcy Donelson of AllMusic said: "The album's 17 tracks address subject matter including breakups, grief, and struggles with mental health with a mix of pop, R&B, and alternative stylings.
