Ooooof.

As if the news of 2NE1's disbandment didn't already contribute to our ongoing Seasonal Affective Disorder, the fact that they're — or, at least YG Entertainment is — serving up one final single in the form of a CL-penned song this month called "Goodbye" is even more of a devastating blow.

Today (Jan. 19), the 2NE1 sign-off just got even realer.

YG just shared the first teaser poster for 2NE1's "Goodbye" on Instagram, featuring the girl group blurred in the background with a girl mournfully contemplating in front of the photo. Agonizing, genuinely. Like, COME ON.

The song, which was co-produced by J Gramm and Rook Monroe, will be released on January 21. As we previously reported, the song was originally intended for CL‘s U.S. solo career, written “as an outlet for the leader’s feelings of regret about the end of 2NE1.”

Gather your tissues accordingly.
