Shawn Mendesis feeling nostalgic about his recent breakup.

While speaking about his new music, the 23-year-old Canadian singer couldn’t help but reflect on his life after splitting up from his former girlfriend,Camila Cabello.

The “Treat You Better” singer posted a video onTwitterFriday where he opens up about how his new lyrics reflect his real life struggles.

“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? And I think that’s the reality that kinda I am on my own now after like, finally I am actually on my own and I hate that … that’s my reality, you know.”

Last November, Mendes and Cabello, 25, announced they hadparted ways after two years of dating,claiming at the time they would “continue to be best friends.”

Earlier this month, the former Fifth Harmony singer appeared toaddress her splitfrom Mendes through her newest single, “Bam Bam.”

“You said you hated the ocean/But you’re surfin' now/I said I’d love you for life/But I just sold our house,” Cabello sings in the opening lyrics.

Coincidentally, Mendesshared photos of himself surfingon Instagram days after their split, despitetelling fans years earlierthat his “weirdest fear” involved a full-blown panic attack while swimming in the ocean at nighttime.

Cabello, meanwhile,sold her three-bedroom Los Angeles mansionin December, one month after she and the “Wonder” singer broke up.

“I feel like the most powerful thing is to zoom into the super, super details of it, basically saying it without saying it,” Cabello told Zane Lowe on Apple Music 1’sNew Music Dailyof her lyrics.

For his recent cover story interview withBillboard, the “Mercy” crooneropened up about his newfound inspirationto focus on leaving his mark on the music industry.

“For me, it’s not to be like, ‘I have to change the world,'” Mendes told the outlet. “I’m just saying, that’s where my ambition goes — to influence culture. I want to honor the opportunity that I’ve been given as an artist, to make something very true.”

Moving forward, the star is working on a new album and is gearing up for his Wonder World Tour, which kicks off in June in Portland, Oregon. At the end of the day, however, it’s about the music — not the size of the venue — for Mendes.

“There was a long while where I was convinced that you just had to write big songs,” Mendes shared. Now, his priorities have shifted: “The type of music that I want to make, what I want to hear, and what is important to me.”
