We live different realities. Treat the hormones.

Two realities#

There is the world as it is. Gravity. Blood glucose. What someone actually said. Whether the rent cleared. That is objective reality. It does not care how you feel about it.

Then there is the world as it lands on you. Threat or safety. Meaning or grey mush. Desire or nothing. Patience or a hair-trigger. That is subjective reality, and it is not a free-floating soul-state. It is a body reporting on a body.

Hormones are a big part of that report.

Same office. Same partner. Same email. One week you can take the hit and still choose. Another week the same sentence is an attack and the day is already lost. Nothing mystical happened. The filter moved.

I have written about twenty years of depression that turned out to have a hormonal contributor, and about why feeling more is not the same as emotional intelligence. This is the connecting piece. We do not all live the same reality. If you want to fix a lot of human issues, treat the hormones.

None of this is medical advice. I am not a doctor. I am someone who spent a long time arguing with a mood that was partly a measurement problem.

The filter is not optional#

Your brain does not receive the world raw. It predicts, samples, and weights. Stress chemistry is one of the weights.

Acute stress knocks prefrontal control offline. Working memory drops. You get shorter, more reactive, more amygdala. That is not a character flaw arriving on schedule. That is cortex losing the vote.

Cortisol is the obvious lever. Chronic high stress does not only make you "feel stressed". It changes what looks urgent, what looks insulting, and how much recovery you get from sleep that looks long enough on paper. Hypercortisolism and glucocorticoid excess are tied to mood disturbance, anxiety, and cognitive fog. The reverse is true too: depression and broken sleep push the axis around. Chemistry and story feed each other.

Thyroid is the quieter one. Overt and even subtler thyroid dysfunction show up as depression, anxiety, cognitive slowing, and flat energy that get treated as personality or as "the depression" for years. People argue about mindset while T4 and TSH sit in a drawer nobody opened.

Sex steroids are the ones people moralise fastest. Low testosterone in men tracks with fatigue, low drive, depressive symptoms, and a world that has lost its colour. Across the cycle, oestrogen and progesterone shifts are not vibes. PMDD is a clinical demonstration that the same life can become intolerable on a hormonal timetable, with real functional impairment and suicide-risk elevation in the late luteal window for the people who have it. That is not "being dramatic". That is a nervous system riding a signal.

Insulin and metabolic mess belong in the same conversation. Insulin resistance associates with current major depression and greater symptom severity. Hunger, irritability, brain fog, and shutdown are not always childhood. Sometimes they are lunch plus a pancreas that has been ignored.

Oxytocin and the bonding chemistry get oversold in airport books, but the point still stands: attachment, trust, and "how safe does this person feel" are not only philosophy. They are partly peptide signalling. Treat the relationship only as narrative and you miss the body that has to hold the narrative.

The pattern is boring once you see it. Hormones do not invent facts. They change the gain on facts. Objective reality stays put. Subjective reality swings.

Why we keep missing it#

Culture prefers a story with a villain.

If he is flat, he is avoidant. If she is sharp, she is toxic. If someone cannot get out of bed, they lack discipline. If a couple keeps exploding at 9pm, they need better communication tools. Sometimes that is true. Often it is incomplete.

It is easier to sell therapy language, productivity advice, and moral judgement than a morning blood draw. A GP has ten minutes. A timeline has a take. Neither has much room for "what is this person's free T, TSH, ferritin, vitamin D, HbA1c, and sleep apnoea status?"

So we argue inside the filter.

We tell people to reframe thoughts that are being amplified by cortisol. We tell men to open up when their drive system is on the floor. We tell women their suffering is personality when the luteal window is doing something specific and measurable. We call metabolic misery "laziness". We call thyroid fog "anxiety". We call low-T anhedonia "who he really is".

I am not anti-therapy and I am not anti-responsibility. You still have to choose. Regulation is still a skill. Feelings are still data, not a verdict. The point is narrower: if the signal is broken, coaching the output forever is a weird hobby.

Depression is a description, not an explanation. Same for rage, apathy, jealousy, shutdown, and "I do not feel like myself". Those words name the weather. Hormones are sometimes the pressure system.

Treat the hormones#

If a lot of human conflict is two filters colliding, then fixing only the story is half a job.

Treat sleep apnoea and the marriage changes. Treat thyroid and the "anxiety disorder" softens. Stabilise blood sugar and the afternoon monster gets quieter. Address clinically low testosterone in a symptomatic man and the grey lifts enough that therapy can actually land. For people with PMDD, targeted treatment of the hormonal sensitivity is not indulgence. It is the intervention that matches the mechanism.

The research is mixed in the places you would expect. Not every low mood is endocrine. Not every hormone panel explains a life. The arrow points both ways: depression and stress suppress hormonal axes by themselves. That is why measurement and a proper clinician beat a podcast protocol.

But the direction of travel is still clear. Before you rebuild a personality, check the hardware.

Ask for bloods. Morning total testosterone twice if you are a man with the fatigue-libido-flatness cluster, with LH, FSH and SHBG. Thyroid panel, not a shrug. Ferritin, B12, folate, vitamin D, HbA1c, lipids, liver and kidney. Look at sleep properly if you snore and still wake destroyed. Women: track the cycle against symptoms instead of gaslighting the pattern. Metabolic health counts. Body composition and training are hormone interventions whether the wellness industry brands them that way or not.

Then be honest about what you will not out-think. You cannot affirm your way out of frank hypothyroidism. You cannot communicate your way out of untreated severe sleep apnoea. You cannot mindset your way through a sex-steroid crash forever and call that growth.

Objective reality includes your labs. Subjective reality is what those labs help produce. Ignore the first and you will keep mythologising the second.

What this is not#

This is not "everyone needs TRT". It is not "women are hormonal, dismiss them". It is not "skip the psychiatrist and buy a vial". It is not a claim that trauma is fake or that poverty is a peptide.

It is the claim that a huge amount of what we call character, compatibility, mental illness, and moral failure sits downstream of signalling molecules we can measure, and often modify, and routinely do not bother to look at.

I lost years to a mood everyone treated as a story. The story mattered. The testosterone mattered too. The useful move was not picking a tribe. It was opening the question again.

We all live reality differently. That difference is not only culture, childhood, and taste. It is chemistry. Objective reality is still there, waiting, while the filter lies to you in high definition.

If you want to fix a lot of human issues, treat the hormones.
