The break-up song teaches moving on and loving yourself more than anything else. The song included some of Ariana's past lovers and how she managed to get over from one ex to another-- citing self-love as her to key to moving on.

In a Twitter thread, the songstress revealed what changed for her since releasing the song. While she thanked the people who supported her throughout her journey of finding and loving herself again, her celebration turned quite into a rambling.

She wrote her song a happy birthday greeting on Twitter and expressed how she has been spending more time alone this year than she had in her life. She also mentioned about her visits to the therapist.

"I can't believe how many sessions w my therapist i've had, how many times i've sung this song, how much I've learned and healed, how much I still have to learn and heal!" Grande wrote on Twitter.

Ariana also clarified that she is not dating anyone currently, as she admitted that she still doesn't know love or have any clue about what a personal life looks like. However, she emphasized that she is perfectly happy with hanging around with pups and piggy, of which the singer realized is already more than enough.

The 26-year-old artist then ended the Twitter thread by sharing how happy her heart is despite still having questions in her mind. Nevertheless, she expressed her love to her supporters, who helped her feel whole once again.

"Thank U, Next" was released as the lead track of Ariana's 2019 album. In the song, Ariana shared about her past relationship, including former fiancee Pete Davidson and late rapper Mac Miller.
