Think about the first few spring days. The sun is shining brightly. The air is warm. The birds are singing. Something shifts in you in a way that feels almost euphoric. Windows down, music up, a sense of buoyancy that had been completely absent for months. Winter fading into a distant memory. The heaviness lifting. Color returning to a world that had gone grey.

And grey is not a metaphor. For you, winter is genuinely muted — dark skies, bare trees, dead grass, streets chalked white with road salt. The contrast when spring arrives isn’t a mood shift. It’s a full sensory event. Your nervous system, which has been in a kind of enforced low-stimulation hibernation, suddenly has something to work with again. Light. Warmth. Sound. Color. Movement.

You probably barely left your bed in January. You hid from people, from responsibilities, from the weight of existing in a world that felt like it was pressing down on all sides. You froze — sometimes literally, dysregulated and cold in ways that had nothing to do with the thermostat. If you have dysautonomia, winter isn’t just unpleasant. It’s a physiological gauntlet. The cold constricts your blood vessels. Pressure changes destabilize your autonomic system. Your body spends four months white-knuckling through tasks that other people don’t even notice, and the exhaustion is invisible to almost everyone around you, including, probably, most of your doctors.

And then April arrives. And you feel free.

And then someone calls it a red flag.

The Moment Everything Gets Complicated

Maybe it was a provider who noticed the pattern — low in winter, elevated in spring — and reached for a bipolar diagnosis. Maybe it was a mood tracker app that flagged your good weeks. Maybe it was a family member who said you seemed “too happy” and looked worried about it.

The elevation is real. The contrast is dramatic. It repeats every year. It looks, from the outside, like cycling.

But here’s the question nobody asked you: when you feel elevated in spring, what does that actually feel like? Does it feel like you’ve finally reached ground level — after months of living forty feet below the surface in a pit? Or does it feel like you’re floating untethered high above the earth, watching everything from the clouds?

Both are elevations from a previous state. But one is returning to yourself after a long winter underground. The other is something else entirely.

They are not the same thing. And if nobody has asked you that question, you may have been handed a diagnosis that doesn’t belong to you.

What Your Body Is Actually Doing

If you have dysautonomia — whether that’s POTS, orthostatic intolerance, or any other flavor of autonomic dysfunction — your nervous system does not regulate quietly in the background the way it does for other people. It reacts. To temperature. To light. To barometric pressure. To the position of your body in space. To stress, to seasons, to everything.

In winter, you are likely running a physiological deficit that nobody can see on a blood test. Reduced light disrupts your circadian rhythm. Cold temperatures constrict your blood vessels and force your heart to compensate. Pressure changes send your autonomic system into instability. The result is fatigue, brain fog, low mood, and a pull toward staying horizontal that feels moral but is actually mechanical. Your body is conserving resources because it has to.

Spring reverses much of that. Longer days reset your sleep-wake cycle. Warmth improves your circulation. Your autonomic nervous system, which has been in emergency mode for months, finally gets to regulate. And you feel it — immediately, physically, undeniably.

Now add the autism and AuDHD piece. Your nervous system doesn’t process sensation at background volume. It processes it at full signal. Winter, with its sensory monotony, isn’t neutral for you. It’s deprivation. And spring, with its explosion of warmth and color and light and sound, isn’t just pleasant. It’s nourishing at a level that is genuinely biological.

This is not mania. This is your nervous system finally getting what it needs.

Why You Might Have Been Misdiagnosed

Autistic people, and people with AuDHD, are misdiagnosed with bipolar disorder at striking rates. Especially women. Especially people who were diagnosed late.

Here’s why it keeps happening. You feel things intensely — that’s not a character flaw, it’s neurology. When you swing between the weight of February and the relief of April, and you express that contrast visibly and physically, it looks to an untrained eye like someone who is cycling. Your variable presentation across seasons gets read as mood instability rather than what it actually is: a sensitive nervous system responding to a dramatically different environment.

If you also have ADHD, the spring picture gets even easier to misread. The dopamine system in an ADHD brain is already running on a different fuel schedule than neurotypical brains. When spring arrives and suddenly the world feels interesting and accessible again, you may launch into seventeen projects simultaneously. Your energy is high. Your sleep is shorter. You’re making plans, making calls, making things happen. From the outside, that looks like hypomania. From the inside, it feels like finally being able to function.

And the crash, if it comes, isn’t a mood cycle completing itself. It’s sensory overload. It’s exhaustion from doing in two weeks what your dysautonomic body can’t actually sustain. It’s the bill coming due on a burst of living you couldn’t help but spend.

That’s not bipolar disorder. That’s your nervous system being exactly what it is.

Questions Worth Asking Your Provider

If you’ve been given a bipolar diagnosis and something about it has never quite fit, here are the questions worth bringing into the room.

Does my elevation actually follow the seasons?

If your “hypomanic” episodes reliably arrive in spring on one of the first warm days and your depressive episodes reliably arrive in winter, that’s a pattern worth interrogating. True bipolar cycling doesn’t follow the calendar this neatly.

Am I above my baseline, or am I at it?

This is the most important question. If spring is the only time you feel like yourself — capable, clear, present — the problem may not be spring. The problem may be everything else.

Has anyone looked at my autonomic function?

Heart rate variability, orthostatic changes, temperature regulation, heat intolerance — these are data points that belong in a psychiatric evaluation when dysautonomia is in the picture. If nobody has asked about them, you’re working with an incomplete chart.

Does my elevated state feel solid or fragile?

In true bipolar hypomania, there is often an undercurrent of instability — a sense that the floor could drop. It tends to come with impaired judgment that the person can’t see in the moment: impulsive decisions, financial choices that won’t make sense later, relationships pushed past their limits, a confidence that outpaces reality. The elevation feels real but the ground underneath it isn’t.

Spring activation in autistic and dysautonomic people often feels the opposite. Clear. Grounded. Like finally being able to think straight. The decisions you make in April aren’t ones you’ll be cleaning up in June. You’re not spending money you don’t have or blowing up your life. You’re returning emails. You’re cooking actual meals. You’re remembering why you chose the work you do. That’s not hypomania. That’s baseline. And the fact that it feels elevated just tells you how far below it you’ve been living.

What happens if I’m medicated through it?

If you’ve been on mood stabilizers and what they’ve mostly done is flatten the periods when you felt most functional, that’s clinical information. It belongs in the conversation.

What It Costs to Carry the Wrong Label

Diagnostic labels follow you. They shape how every future provider reads your chart before they’ve said a single word to you. They determine what gets tried and what gets dismissed. They become part of the story you tell yourself about who you are and what you’re capable of.

If you’ve spent years believing that your spring energy is a symptom of a broken brain — something to be afraid of, something to be managed down — you’ve been living inside a story that may not be yours. You may have been medicated through the only weeks of the year when your nervous system was actually regulated. You may have learned to distrust the version of yourself that feels good.

That’s not a small thing. That’s your relationship with your own mind.

You Deserve a Diagnosis That Actually Fits

At Capstone Mental Health, we start with you — your neurotype, your autonomic history, your sensory experience, your pattern across time. We ask whether a diagnosis explains what’s actually happening in your body, or whether it just describes what it looks like from the outside.

If something about your bipolar diagnosis has never quite fit, if spring has always felt like relief rather than a warning sign, if you’ve spent years being told that feeling good is dangerous — we’d like to talk.

Because you may not be cycling. You may just finally be warm.
