You’re scrolling through old photos again. You don’t mean to, but your fingers remember the path too well. That trip to the coast. The way their eyes looked in sunlight. A smile that once made you feel like you’d found home.
You tell yourself to move on. But it’s like your body won’t listen. Your chest aches, your focus scatters, and part of you keeps reaching—hungry, haunted—for a love that no longer exists.
Why does heartbreak feel like this?
Why does it hurt so deeply, linger so long, and leave us questioning our sanity?
Because love is a drug. And losing it is withdrawal.
Why falling in love feels like being high
Falling in love isn’t just poetic—it’s chemical.
When you’re in early-stage love, your brain floods with dopamine, the same feel-good neurotransmitter released during cocaine use. The ventral tegmental area (VTA) and caudate nucleus light up—regions deeply tied to motivation, reward, and desire.
This explains the rush, the obsession, the focus.
You replay their words.
You check your phone compulsively.
You stay up thinking of them and wake up craving them.
This isn’t weakness. It’s biology.
In one study, brain scans of people newly in love showed activation in the same circuits seen in drug highs. Love isn’t just a feeling—it’s a neurochemical drive.

So what happens when love ends?
The brain doesn’t just grieve—it craves. The same pleasure centers now pulse with pain and yearning.
- The nucleus accumbens (a reward region) lights up
- Craving circuits respond as if deprived of a substance
- You feel physically sick, unfocused, and empty
These aren’t just emotional symptoms. They’re neurological withdrawal reactions. Your brain is screaming for the dopamine it’s lost.
That haunting pull toward your ex?
That fog you can’t escape?
It’s not in your head. It’s in your brain.
Is love really an addiction?
Short answer: yes. But it’s a special kind of addiction.
Early romantic love and drug use both activate the mesolimbic dopamine pathway, the brain’s motivation and reward hub.
But here’s where they diverge:
- Love can evolve into bonding and oxytocin-fueled connection
- Addiction narrows into compulsive, rewardless repetition
So yes, love is a drug, especially in the beginning.
And heartbreak? It’s not just emotional—it’s biochemical.
You’re not weak. You’re withdrawing from something your body believed it needed to survive.
Love, in all its forms, shapes us.
It bonds us, drives us, teaches us joy—and sometimes, breaks us open.
But in that breaking, there’s something sacred:
The reminder that we were wired to connect.
To feel.
To risk.
And eventually, to heal.
Researchers have shown that early-stage romantic love activates dopamine-rich brain regions—like the ventral tegmental area and caudate nucleus—just as cocaine and other addictive substances do. This neural overlap makes love feel exciting, obsessive, and deeply rewarding.
After a breakup, the brain’s craving centers—such as the nucleus accumbens—become hyperactive, triggering symptoms like intense longing, disrupted sleep, and mood swings. These mirror the neurological withdrawal symptoms often seen in substance addiction.
Yes. Recognizing that heartbreak involves actual withdrawal can reduce feelings of shame or weakness. This awareness empowers you to treat the experience with the same compassionate strategies used for overcoming addiction.
Not exactly. While love and addiction share early-stage brain chemistry, healthy love typically evolves into stable bonding through oxytocin pathways. Addiction, by contrast, often leads to compulsive behavior detached from genuine reward.
