Trust My Lonely

"Trust My Lonely" is a pop track with elements of reggae featuring "plinking" synthesizers that lyrically concerns moving on from a relationship.[3][4][5] iHeart Media wrote that the song "has lyrics that bounce between being hurt by a former partner and finding the strength to move on."[6] Cara told Billboard that "When I initially wrote that song, I wrote it because of my insecurities. I think a lot of people, we become comfortable in our misery or comfortable in a relationship that may be bad for us. This song was just a reminder for me and for everyone to just trust yourself and let go of things don't serve you in a positive way, especially your heart and your soul."[7]

The song was written by Alessia Cara, Warren Felder, and Andrew Wansel.[8] Recorded in May 2017,[9] it was one of five songs on The Pains of Growing that was produced by the duo Pop & Oak, who had previously produced Cara's breakout hit, "Here."[10]

Ryan Reed of Rolling Stone called the song "self-empowered" and judged it to be about Cara "crav[ing] independence".[5] Julia Lennox of ET Canada characterized its lyrics as "empowering" and called it "groovy" with "trendy trap beats".[3] Variety labelled it a "breakup song".[2]

A music video was released for the track featuring Cara dancing in a variety of settings, including on a beach and in a field, as well as in front of a number of colored backgrounds,[11] which Rolling Stone deemed "playful, colorful" and "lighthearted".[5] In the video, Cara is wearing the same oversize suit as she did in the music video for her previous single, "Growing Pains."[12] Regarding the suit, she said during a September interview on the Today Show that "It's like an artistic way of symbolizing the idea of growing up [...] Sometimes you kind of feel like you're drowning and you feel like you're not ready for the roles life throws at you, so this was my way of symbolizing it in an artistic way."[13]
