HotNewHipHop compared "SAD!" to the singles on X's debut album, 17 due to its emo hip hop aesthetic, saying "Once again, the young Floridian is veering into emo territory — with a lo-fi synth string loop and crisp percussion, the melodic ballad showcases X's ear for melody." XXL noted how the "upbeat instrumental" varied from the lyrics that shown XXX "struggling with depression and suicide over an ex-lover." Rap-Up also pointed out the "emo-melodies" that surround the track and spoke on the theme of suicidal thoughts over an ill-fated romance.

The music video for Onfroy's "SAD!" premiered one day after his memorial service at the BB&T Center on June 28, 2018. The video was written and "creative directed" by Onfroy himself, and directed by JMP. In the video, an older X attends the funeral of his younger self, which has his older split-dye yellow-black hair, the same hairstyle that was present in X's famous mugshot after being arrested on domestic violence charges. When X approaches the casket to look at his younger self, the younger X suddenly returns to life. The two begin fighting in the church and out in the alley. Before, during, and after the fight, a dark hooded figure speaks to X, asking various questions and advocating for a way of thinking centered on love rather than hate and for X to realize that the biggest enemy in his life has been himself. X defeats his younger self and leaves him lying on the ground in a completely white location. A piece of paper appears on the screen that reads, "People change, things change, and so did I." The video concludes with the words "LONG LIVE PRINCE X". Many interpreted the music video as a final message of remorse from X for his past actions. The video has over 161 million views across YouTube as of March 2023. The audio has over 1.2 Billion views as of March 2023, making it his most popular YouTube video.
