Love addiction: healing an attachment loop

The stimulation the relationship provided is gone. Brain-imaging studies show that separation affects the reward and attachment circuits (dopamine/oxytocin); the exact hourly resolution varies from person to person.

The brain may process the absence of the attachment figure like a threat; the stress response (HPA axis, cortisol) kicks in. Its intensity and timing vary from person to person.

It has been shown that social rejection and separation can activate brain regions that overlap with physical pain (e.g., the anterior cingulate cortex); there may be a real feeling of tightness in the chest. Individual variation is large.

Old motor habits in the striatum kick in. Your fingers automatically reach for the phone, and the urge to check your partner's online status, photos, or old messages peaks.

Studies on love and separation suggest that intense passionate attachment may be linked to low serotonin (a pattern similar to that seen in OCD). This may explain the constant rumination and obsessive scenarios.

Because of high cortisol and adrenaline, melatonin release is suppressed. The body stays awake at night, sleep architecture is disrupted, and repeated waking episodes occur.

Levels of vasopressin, the hormone of social protection and partner bonding, crash. You feel utterly unprotected, insecure, and alone in the world.

Dopamine receptor desensitization peaks. Eating, listening to music, or talking with your friends feels utterly meaningless and tiring.

Because of the sympathetic nervous system's uncontrolled noradrenaline release, sudden hot flashes, rapid breathing (hyperventilation), and a feeling of panic are triggered.

As the dopaminergic flow to the forebrain (prefrontal cortex) weakens, you experience cognitive fog, loss of focus, and an inability to make sensible decisions.

The hypothalamic-pituitary-adrenal axis is hypersensitive. The slightest trigger (a scent, a song, or an old belonging) sets off crying spells and deep waves of sorrow.

To ease the withdrawal crisis, the brain seeks an artificial dopamine/oxytocin discharge by looking at old photos or listening to old voice recordings.

Constant sympathetic stimulation (being on alert) causes micro-spasms in the shoulder, back, and neck muscles. Chronic clenching of the jaw muscles (bruxism) appears.

The most dangerous autonomic wave brought by the acute abandonment shock comes down from its peak. The mind begins to accept the permanence of the situation.

The parasympathetic system kicks in. The resting pulse calms, and autonomic nervous system homeostasis begins to be re-established.

Release of the stress hormone cortisol recedes to steady limits. That intense nausea and morning anxiety felt on waking eases.

The pain pathways in the anterior cingulate cortex calm. By producing its own natural endorphins, the brain markedly eases that somatic pain in the chest.

The absence of extreme stimulation triggers the dopamine receptors (D2) to increase their sensitivity and number (upregulation).

The circadian rhythm improves. The proportion of deep NREM sleep in night sleep rises, and synaptic cleanup begins at the cellular level.

The prefrontal cortex filters the tendency to remember only the partner's good sides (the idealization cognitive error). Toxic truths are logically accepted.

The acetylcholine balance in the hippocampus is established. That intense brain fog after the separation disperses, and memory and focus return.

The strength of the habit bridges in the striatum weakens. During the day, the urge to look at their profile or check their online status decreases markedly.

The sympathetic startle response (adrenaline spike) given to every incoming message in the expectation that it might be from the partner fades.

The brain begins to respond not only to stimuli from the partner but also to secure oxytocin sources like friendship, family, and pets.

The neural pathways between the reasoning lobe (prefrontal cortex) and the impulse lobe (striatum) strengthen. Willpower easily blocks the urge to contact the partner.

With sympathetic/parasympathetic balance established, Heart Rate Variability (HRV) rises. Your body's resistance to emotional stress increases.

The gastrin and stomach acid production triggered by chronic anxiety normalizes. Stress-related bloating, loss of appetite, or stomach cramps pass.

The chronic sympathetic tone (tension) in the shoulder, neck, and back muscles releases. Body posture relaxes, and muscle aches ease.

The brain starts responding to small natural stimuli. A tasty meal, exercising, or working toward a new goal creates a clean dopamine release.

The neural action loop of automatically turning to the partner or texting them in moments of loneliness or boredom fades.
