What is “Denial Is A River” by Doechii about?

"Denial is a river” is a saying made popular by famous talk show host Wendy Williams. During an episode of The Wendy Williams Experience, Williams coined the phrase “Denial is a river in Egypt, your husband is GAY!,” likely alluding to the popular idiom “Denial is not just a river in Egypt,” or variations of that line. Doechii and DJ Miss Milan even channeled the Williams’s iconic moment as the MV’s final pre-release teaser. But the rapper’s song has a different meaning than Willams’s phrase. The track breaks down the different experiences she’s had in her personal and professional life over the years. How to use this trend?
