In this short, Dr. Tabatha Barber recounts her early‑20s struggle with depression and the experience of being prescribed three psychiatric medications without any objective brain testing. She describes a pivotal moment when she left her psychiatrist’s office, felt the sky turn blue and the trees turn green, and realized that changing a single thought could instantly shift her biochemistry. She frames this insight as an "inner pharmacy," arguing that thoughts can alter neurochemistry within 150–300 milliseconds, giving individuals daily control over their emotional state. Barber critiques the psychiatric practice of prescribing based on unmeasured "chemical imbalances," cites Dr. Amen’s work on brain imaging, and highlights modern neuroscience concepts—neuroplasticity and epigenetics—as evidence that the brain can be reprogrammed. The overall message is empowering: we are not stuck with a fixed brain chemistry; by consciously shifting thoughts we can heal ourselves.

When I was in my early 20s and I had my first job, I had health insurance and I was struggling with depression. So I went to a psychiatrist, left the psychiatrist's office. I was on 3 mind-altering medications in my early 20s. And ultimately I ended up going back one last time after months and months. And I, it was a God moment, woke me up inside.. And I just, I had to leave that office. And I remember I went outside and it was like the sky was blue for the first time. The trees were green. And I was like, okay, like you get to heal yourself. You're the only person that can make you happy. And through my journey I learned, I was like, oh my gosh, there's no way to measure brain chemistry. But that doctor told me, oh, you probably have a, a chemical imbalance in your brain, so we're gonna put you on an SSRI. He never scanned my brain, never looked at my brain, never took my blood. There was nothing. And I'm like, as I've studied the brain and looked at like Dr. Amen's work is amazing as well. I'm like, the brain is the only organ in the body a doctor doesn't scan, look at, or anything before they medicate it, before they treat it. That's wild. Yet it's running everything. That is, I mean, like if we sit back, this is wild stuff. Yeah. Right? And so when I learned that, I was like, oh my goodness. And then what's crazy is that moment I walked out of that psychiatrist's office that day, why was the sky blue for the first time to me? Why were the trees really green? Why did I have this sense of power and energy within my body? Because I shifted my thinking. Yeah. I changed a thought, which changed my biochemistry. And it's been proven in science Your biochemistry can change in 150 to 300 milliseconds by shifting the thought alone. That is power, my friends. Like, that is your inner pharmacy. So every day we wake up, we are choosing our prescription. We are choosing how we are going to feel. We are choosing our thoughts. And when I started to realize this, I was like, oh my gosh, like, I can literally reprogram my brain. It was the first time, like, I had hope for myself. I thought I was like doomed by the brain I have. And then we look at neuroplasticity and neuroscience and what that's teaching us and epigenetics. And I'm like, oh my gosh, I wanna scream it from the rooftops. Like, we are not stuck with where we're at, how we're feeling. We get to change that. And so that's exciting stuff to me.
