Thu, June 26

You meet someone. They're cute. They laugh at your jokes.

Suddenly, you can't stop thinking about them. You're daydreaming in class, re-reading their texts, and smiling at your phone like a rom-com character. But wait β€” why does this feel so intense?

Well, spoiler: it's not just feelings, it's your brain chemistry. That unsteady, almost-addicted-to-their-existence sensation? It's your brain doing what it was wired to do.

Let's break down exactly why teenage love feels like a literal emotional rollercoaster, and why it's totally normal to feel like you're spiralling (a little).

Let us slide into your dms πŸ₯°

Love is Brain Chemistry (Yes, Really)

When you start crushing hard, your brain goes wild with chemicals. Here's what's happening behind the scenes:

First, there goes dopamine. This is the "feel-good" chemical. It gives you that rush every time your crush texts you or smiles at you in the hallway. It's the same chemical that lights your brain when you eat your favourite snack or achieve something exciting.

Next, usually after a few hangouts, comes oxytocin: also known as the "bonding hormone," this one kicks in during hugs, deep conversations, and emotional closeness. It makes you feel safe and connected.

And there's also serotonin, which ironically drops when you're crushing on someone. That's why you feel obsessed, distracted, or even anxious β€” like your brain is prioritising them over everything else (Serotonin is usually the reason you push your friends a bit away when having a crush).

So basically, your brain is literally setting off fireworks, and you're just along for the ride.

Why Teens Fall So Hard (and Why Some Fall Even Harder)

Teen brains are still developing, especially in areas like impulse control, emotional regulation, and risk assessment. So when love chemicals β€” dopamine and oxytocin β€” surge, they hit harder than they would in an adult brain.

It's why teen love can feel like the most intense, consuming thing ever β€” even if you've only known the person for a few weeks. Your brain is learning, bonding, and craving connection all at once.

Some teenagers might fall in love, or even crush on someone, a lot harder than the others, and guess what? That's not silly or dramatic. It's legit neuroscience.

Studies have proven that extroverts tend to catch feelings much faster than introverts. Different levels of estrogen or testosterone also affect how fast and intensely someone might fall for someone else. And if your brain produces more oxytocin or vasopressin, which play a role in bonding and attachment, you're more likely to feel attached super fast.

Everyone's love experience is a little different β€” because everyone's brain chemistry is a little different. And that's totally normal.

Love or... Addiction

Okay, this might sound dramatic... but falling in love actually does resemble addiction.

Studies using brain scans show that people in love β€” or going through a heartbreak β€” have brain activity similar to those withdrawing from addictions. The cravings, the euphoria, the obsessive thoughts? All of that can be tracked back to dopamine and your brain's reward system lighting up like it's on fire.

So if you've ever felt you couldn't stop thinking about someone, or like their absence physically hurts β€” you're not being clingy or too much. You're just human. Your brain just doesn't know the difference between romantic love and a reward it desperately wants more of.

That's also why getting over someone can feel so confusing. One second you're numb, the next you're crying over a memory you swore you were over. That obsession-sadness-numbness cycle? It's your brain trying to recalibrate β€” literally rewriting its wiring like it would after a major loss or addiction recovery.

When the Dopamine Drops: Love's Crash Landing

If love is a high, heartbreak is the crash.

When something in the relationship shifts β€” like a ghosting situation or a breakup β€” your brain gets confused. The dopamine and oxytocin that were flowing? They suddenly dry up.

You might feel numb, sad, anxious, or totally unmotivated. That's your brain dealing with losing something (or someone) it was chemically attracted to.

That is also why the no-contact rule is so effective: avoiding your crush or ex helps your brain slowly deactivate those chemicals and move on.

So... What Now?

Teenage love is real love.

But it's also a combination of brain chemistry, hormones, and connections inside your still-developing brain. That's why it feels like you're flying one minute and crashing the next.

So the next time you catch feelings hard β€” or feel like you're drowning in a sea of "what ifs" β€” remember:

You're not being dramatic.

You're just human. And your brain is doing exactly what it was designed to do: fall, feel, bond, break, grow, and heal.
