As teenagers, we're expected to be brooding and moody. It's the one time in your adolescence that you're allowed to be mean, rude, or a host of other negative things."He/she's just being a teenager, after all," you'll hear people say. It's your free pass; it's almost expected of you.

One of the most infamous stereotypes is the angsty teen, sitting in their room, music blasting from headphones, throwing a baseball against the wall. What are they thinking about? Their childhood? Someone they like? Or maybe they're just really hungry. The world may never know.

Then why are these feelings of angst, apprehension, anxiety, and being misunderstood, suddenly expected to go away at the age of 20? Does moving onto adulthood suddenly mean we can't have days where we feel unmotivated or just like lying in bed listening to our iPods? No, but that's how society makes us feel.

An article by the Independent explains why teenagers have gained such a moody rep. Elsa Vulliamy explains, "Given that they’re dealing with change in sleeping pattern, heightened anxiety, a propensity to respond emotionally and a desperation to be recognized by peers it is unsurprising that teens appear to be moody and disagreeable – it actually seems like they might be coping rather well." So fair enough, teenagers have a lot of factors contributing to their overall moodiness. No intention to discredit these feelings, because, let's be real, middle school was the worst, right?

But, that doesn't mean that these feelings magically go away once we reach adulthood. As we age, we're expected to tackle more responsibilities and therefore are put under additional stress.The WSJ's article, Delayed Development: 20-Somethings Blame the Brain, says, "recent research into how the brain develops suggests that people are better equipped to make major life decisions in their late 20s than earlier in the decade. The brain, once thought to be fully grown after puberty, is still evolving into its adult shape well into a person’s third decade, pruning away unused connections and strengthening those that remain."

Not to mention, early 20s are often an unpredictable, tumultuous time in terms of education, career, and life decisions. Aside from the lucky few, most people are just trying to figure out what they want to do with their lives and how they can make that happen. So it's bound to occur that days full of stress, worry, anxiety, and yes even some angst, will creep their way in. So don't feel bad. You're no longer a moody teen; you're just an angsty twenty-something.
