(CNN)Beef jerky, bottled water, and Fireball whiskey. This is where my journey began, at the grocery store, buying "survival" items on Thanksgiving Day.

I was meant to join a gaggle of screaming children at the kids' table. But Gatsby, my ex-race-horse-turned-ungrateful-teenager, had just spiked a 105-degree fever. I was in for a long night.
I hurried back to the barn, parked, locked my car, and started heading in. But something stopped me in my tracks: a familiar, gravitational pull which begins as a small thought in the back of my mind, and pushes its way front and center within a matter of seconds. The sum of all its parts become greater than logic, evidence and truth.
    I walked backed to my car and started the ritual. Tap each window five times. Stop. Go back, and do it again. Check the door locks. Pull each handle up five times. Stop.
    Move to the trunk. Open. Close. Check the lock five times.
    The last trick is to move away from the car without having any "bad" thoughts. I had to keep only "good" thoughts in my mind, because if I didn't do it correctly, a catastrophic event would occur. A friend would suffer a heart attack. My neighbor's dog would get hit by a car. The tree above my bedroom window would come crashing down. But the good news is, I could prevent it all from happening, if I "secure" my car a certain way.
    Am I nuts, you ask? Perhaps. But this is just another day, living with obsessive compulsive disorder, known as OCD.
    Here's a shocker. I missed a tap that night, and absolutely nothing happened.

    Home is where the horse is

    Gatsby was my dream horse.
    Correction: Gatsby was my idea of a dream horse.
    Growing up, my horses were teachers, baby-sitters, co-conspirators and confidants. There were haughty and naughty ponies, and mares who ran through sprinklers with me in the summer.
    A typical afternoon growing up in the 1990s, with sweet Honey Bear and Sandy, the golden retriever.
    But a beautiful thoroughbred with natural athleticism and a born-to-be-bad attitude -- now that was my type of horse.
    But then, life happened. I moved away to college, joined the workforce and started navigating life in Los Angeles, where the pace is always set at a medium-high.
    For years, horses weren't within the realm of possibility.
    But in 2012, I got back in the saddle, and eased back into life at a barn. I befriended a young mare, who was rescued on her way to slaughter outside the United States. She only knew how to do two things: speed-walk, and gallop with her hair on fire.
    Misty quickly became my partner -- we spent our days trail riding, sharing watermelon and developing our own language where words aren't necessary.
    People often ask me why I love horses. This is why.
    Misty was nervous and shy, but what I saw in her was the most soulful being I'd ever encountered. She still is.
    But the dream horse -- a tall glass of water with a confident spirit -- that dream lived on.

    Under lock and key

    My earliest memories of OCD date back to when I was 7 or 8 years old. I lay in bed at night, my mind whirling with thoughts about whether the doors and windows were locked. Mind you, we lived in a safe, rural neighborhood in Encinitas, California, during the glorious 1980s. As kids, we'd ride bikes to the beach after breakfast, eat ice cream for lunch, and return around sunset.
    But when the lights went out, the negative images played on repeat. A home invasion robbery. Broken glass. Gunmen wearing ski masks. Serial killers would finish us off, and terrorize our neighbors. They'd hit up the next street, and the next. The entire town would be wiped out. Gone. My mind would spin and spin. It was annoying as it sounds.
    The only way to settle my thoughts was to give in to the obsession. This manifested itself in a bizarre lock-checking ritual after my parents were asleep.
    I started upstairs, checking six windows and a sliding door.
    Push the locks repeatedly. Stare at it. Still locked? Yup. Repeat. Don't touch it. What if the lock unlocked itself? (There's a riddle for you). Check again. Then tiptoe through the rest of the house. If an intruder dared to climb through our tiny window that a cat could barely fit into, they wouldn't be able to get in anyway. Because it was locked!
    Twenty-one locks, multiplied by two minutes each. It was time-consuming to say the least. And to say the most, OCD robbed me of many peaceful nights in my childhood.

    Born to be wild

    One afternoon in 2014, I was at the bottom of the Rattlesnake trail in Griffith Park, deep in negotiations with a horse named Dunbeath. He was for sale, and I was trying him out for fun. And because he was handsome.
    Did I need two horses ? No.
    Did I need a "beautiful thoroughbred with natural athleticism, and a born-to-be-bad attitude?" Yes.
    I was on the fence. He was feisty, arrogant and a troublemaker -- I knew he'd make me work for his heart and mind.
    So I made him a deal. I told Dunbeath we'd race up Rattlesnake to the highest ridge -- we'd be reckless, stupid and take blind turns with no abandon. If I was still on him when we reached the top, and not in a ditch somewhere, I would keep him.
    Well ... guess who stayed on?
    I changed Dunbeath's name to Gatsby's Mint Julep. But let's be real, I call him G.
    He's not a mean-spirited punk, but he pushes my buttons and drives me to the brink of insanity. Over the years, he's amassed a comedic repertoire, which includes:
    • Screaming and jumping in the air, upon encountering a small pig walking on the street.
    • Crafting a Houdini-style escape from an arena, and trampling someone's rose garden.
    • Kicking me with his giant horseshoes ... because he didn't want to take a bath.
    • Dismantling his entire Mad Hatter Halloween costume (long story) in less than two minutes (short story).
    His penchant for mischief and mayhem is unrivaled. But, he gets credit for never reaching a level of naughtiness I wouldn't be able to handle.
    Because I know he's tempted.

    Hiding in plain sight

    Outside the barn on Thanksgiving, I pulled myself away from my lock-checking extravaganza after four attempts. Round five was cut short by a passing car. I stopped immediately when I saw headlights approach, and let my thoughts fester in my head. By that time, keeping OCD hidden was second-nature to me.
    Old friends, new friends, colleagues, family. Even my Mom had no clue.
    I barely knew it myself.
    The night unfolded in a spectacular fashion. Our veterinarian came out for an emergency field trip and confirmed my worries.
    Earlier that month, the Burbank horse community was dealt a rare outbreak of the equine herpesvirus. The highly contagious virus didn't reach our barn, but the facility next door was quarantined, as mandated by the California Department of Food and Agriculture.
    Several horses were seriously ill, and sadly, others died. A primary symptom of EHV is a high fever, so Gatsby's blood samples were put on a plane to undergo testing at a laboratory in Sacramento.
    At the end of the night, Gatsby was sequestered in a dark isolation area, with only a small window to peer out into the world.


    The following day, I had this great idea to buy a boom box radio so Gatsby could listen to Christmas carols. If you didn't think I was bonkers before ... well, I think this confirms it!
    My ideal Black Friday is spent light-years away from OCD-and-anxiety-inducing retail festivities. But I was on a mission to buy an entertainment system for a horse, so I had to get over myself and go to Target.
    Throughout my life, the intensity of OCD has ebbed and flowed, as I developed new obsessions and compulsions.
    Making contact with certain objects -- like tile flooring and grass -- often leaves me feeling absolutely disgusting until I take a shower. Whenever I pass a public restroom, I experience crippling anxiety over germs in my hair. But the most ridiculous obsession is fear of driving through certain freeway underpasses, where the air flow is restricted.
    Sometimes, my symptoms are on full blast, but there are also blissful stretches where I'm relatively fine. My college years were nearly symptom-free. I was probably too busy making jungle juice to care.
    Hamasaki's first horse, Lindy, an Appaloosa mare who loved to run off as they rode.
    I wish there were a rhyme or reason for this madness. I'm happy spending all day with horses, covered in dirt and bugs. But I avoid walking too close to garbage cans at the barn, so as to avoid airborne contaminants. When I see others touching them with bare hands, my heart starts racing.
    It's the nature of the beast.
    Standing outside Target, I didn't make my usual game plan to avoid "contamination" from certain locations and objects. I went inside wearing mental blinders. Get a cart. Touch it. Push it. Turn left. Get the radio. Batteries. Grab a basketball for Gatsby to play with (or destroy, depending on his mood.) Stand in the checkout line. Don't think. Get in the car and drive off.
    I had to get it done. So I did.
    I spent the next 10 days convincing Gatsby he wasn't part of a strange Medieval science project.
    I brought a camping chair into his stall, and sat there for hours. I did my Christmas shopping online, and scared myself silly reading mysteries in the dark. He ate carrots while I had lunch, and we listened to the news on the radio.
    Meanwhile, the lab results started coming back. The first one was negative. So was the second. On day 11, the third test came back, and he was a free man. We chalked up his fevers to a different virus strain, and he stepped outside, squinting in the sunlight.
    The entire barn celebrated his release. I felt the love, and so did he. I began to think of Gatsby and me as friends. Maybe even family.
    When I arrived at his stall three days later, he wasn't eating breakfast. He stood in the corner, and gave me a withering look. I don't why I said this out loud, but I told him "Nobody puts baby in the c
