You know, when people say your 20s are difficult, they mean your whole 20s. They don't mean that somewhere around your mid-to-late-20s, you start to figure stuff out and settle in. You don't coast into 30 with a bag of answers. Who told you that? Who's been running their mouth about your 20s?! They seem like a know-it-all, honestly (wink!). No, the entire decade is ughs on top of blahs.
I'm here to submit that your late 20s are the worst. You have to fix your early 20s, and it is a bummer.
