Shawn Mendes is still trying to heal from his November 2021 split from Camila Cabello.

While speaking about his new music, the 23-year-old Canadian singer couldn't help but reflect on his life after the breakup.

The "Treat You Better" singer posted a video on Instagram Friday where he opened up about how his new lyrics reflect his real-life struggles.

"I think that's the reality that kind of hit me. It's like, oh, I'm on my own now," the singer said. "Now I feel like finally, like, I'm actually on my own, and I hate that. That's my reality, you know?"

Mendes, who was sitting at a piano and speaking candidly to the camera, added that he didn't realize the aftermath of a breakup.

"You don't realize when you're breaking up with someone … all the s— that comes after it," he said. "Which is like, who do I call when I am, like, in a panic attack, who do I call when I am, like, f—ing on the edge, you know?

Mendes and Cabello, 25, were first linked in July 2019 and announced their split last fall with a joint statement shared to Instagram.

"Hey guys, we've decided to end our romantic relationship, but our love for another as humans is stronger than ever," the statement read. "We started our relationship as best friends and will continue to be best friends. We so appreciate your support from the beginning and moving forward. Camila and Shawn."

Earlier this month, the former Fifth Harmony singer appeared to address her split from Mendes through her newest single, "Bam Bam."

Her duet with Ed Sheeran features her singing about how life can change following a breakup.
