How Do i Know If My Mood Swings Are Hormonal or Mental Health?

Short Answer

Your body doesn't file emotions into "hormonal" and "mental" folders—it only knows safety and threat. Whether the trigger is a drop in progesterone or a perceived abandonment, your nervous system responds with the same biochemical cascade: cortisol spikes, glucose diverts from digestion to muscle, and your window of tolerance narrows until you feel either explosive or shut down. The question isn't which category your mood swings belong to, but how your neuroception—the subconscious detection of safety or danger—has learned to interpret internal fluctuations as threats requiring survival responses. Here is the sentence you haven't heard before: The metabolites of progesterone bind to the same GABA-A receptors that early trauma hyper-sensitizes, meaning your pre-menstrual week biochemically mimics the neural landscape of an attachment rupture. This means your identity isn't fragmenting; you're experiencing an intelligent, if outdated, survival mechanism that treats hormonal shifts as relational emergencies requiring protection at any cost.

What This Means

Internally, it feels like being trapped in a room where the thermostat, lights, and volume control are operated by someone invisible and erratic. One moment you're present, engaged, and coherent; the next you're dissociated behind a pane of glass, watching yourself snap at a partner or weep at a commercial with a sense of horrifying disconnection. Your chest might tighten with a premonitory dread that has no name, or you feel a sudden, shameful heat that seems to originate inside your bones rather than your skin, accompanied by a metallic taste of panic that arrives before any thought. What others witness as "moodiness," "overreacting," or "being difficult," you experience as a terrifying loss of continuity—wondering which version of you is the real one, and whether you're allowed to trust any feeling that arrives without invitation. The cost is a life spent hyper-vigilant about your own interior: you track cycles like weather patterns, apologize for existing, and make yourself smaller during certain weeks, living in anticipatory dread of your own physiology. You begin to gaslight yourself, disowning anger as "just hormones" or dismissing grief as "chemical," until you no longer know what you actually feel versus what your body is metabolizing, and you lose the ability to trust your own emotional compass.

Why This Happens

This pattern often begins in childhood, when your developing nervous system learned that emotional expression was either dangerous or relationally expensive. If you grew up in an environment where caregivers were inconsistent, overwhelmed, or unable to tolerate your big feelings, your body developed a hyper-vigilant scanning system—constantly monitoring for the subtlest shift in emotional weather that might signal abandonment or attack. This early adaptation created a sensitized amygdala and a hair-trigger HPA axis, meaning your stress response activates faster and shuts down slower than those who developed in consistently safe environments. Neuroscience now shows that chronic childhood stress alters glucocorticoid receptor sensitivity and reduces hippocampal volume, essentially priming your body to interpret any internal fluctuation—whether blood sugar drops, estrogen shifts, or cortisol spikes—as a state of emergency requiring immediate defensive action. When puberty arrived, bringing its monthly hormonal surges and drops, your nervous system didn't experience these as neutral biological events; it coded them as the same unpredictable abandonment it had spent years surviving, particularly because progesterone withdrawal creates a biochemical withdrawal state similar to coming down from sedatives. What was adaptive then—staying hyper-alert to internal and external changes, suppressing needs to maintain attachment, fragmenting your experience to survive the unsurvivable, and treating instability as threat—has become maladaptive now. Your body is still doing the job it was hired for: keeping you safe, except now the instability is coming from inside your endocrine system, and the threat response is destroying the relationships and self-trust you need to thrive.
