Miranda Lambert is facing her demons.

The country singer released her new single “Vice” on Monday, and the down-tempo track has some heavy lyrical content.

“Maybe I’m addicted to goodbyes,” Lambert admits on the track, on which she also addresses some habits the title hints at, from drinking (“Sweet salvation on a dining room table / Waiting on me, where the numb meets the lonely / It’s gone before it ever melts the ice”) to carnal desire (“Another call / Another bed I shouldn’t crawl / out of at 7 a.m. with shoes in my hand / Said I wouldn’t do it, but I did it again / And I know I’ll be back tomorrow night”).

Lambert, 32, co-wrote “Vice” with Grammy-winning Nashville songwriters Shane McAnally and Josh Osborne.

And the rueful track is the first the singer has released since she and ex Blake Shelton announced they had divorced last July. The couple had dated for six years and married for another four before calling it quits.

Shortly after Shelton began dating his Voice costar Gwen Stefani last year, Lambert moved on herself with fellow country singer, Alabama native Anderson East, as PEOPLE confirmed in December.

Lambert “is extremely happy and content with how her life is proceeding,” a source told PEOPLE of the singer in March. “She’s having a great time living and working within a creative community.”

Just a day before she dropped her new single, Lambert celebrated her new beau’s 27th birthday, captioning a candid shot of them kissing on Instagram, “Happy Birthday to my favorite ‘Bama’ boy!”
