As someone with the adhd, this is clearly an exaggeration of what I (and others) have felt and still feel on our lives. It has to do with ADHD in the sense that we struggle to conform to society expectations and therefore, we commonly feel behind on life and even with a lot of effort, we struggle to "catch up". Going to therapy helped a lot with self worth, also being diagnosed was really helpful, before that I always was depressed because I could not fulfill expectations due to my focus issues(and other adhd symptoms). Hope this helps to understand this meme and community!
