About Fixmd

fixmd.io is a project I started to make one thing practical: what to do when your PFC goes offline under stress—when you spiral, shut down, overreact, or do things you don’t actually agree with afterward. This site turns that “I don’t want to be like this” moment into something observable, trainable, and reviewable. It’s both my public notebook and a toolbox.

My goal is for the content to be sincere and usable: not reducing complexity to slogans, not mystifying change as talent, but translating the more reliable parts of psychology and neuroscience into actions you can do in daily life.

Who am I?

I’m a software engineer with over ten years of experience, and the initiator of fixmd.io. I’ve been self-studying psychology and neuroscience for years, and I tend to approach problems like an engineer: break the black box into modules, turn “this feels impossible” into testable hypotheses and small practices.

In 2020, I went through a major life difficulty. After that, I read intensively for 3000+ hours (religion, philosophy, history, literature). It expanded my thinking, and at some point even gave me the illusion of being “awake”. But years later, I noticed something blunt: when real stress shows up, old reactions still activate on time.

Over time I realized that many “patterns” are not about willpower or not understanding enough. They’re automatic operating modes of the brain-body system under specific conditions. Understanding doesn’t instantly change them—but it gives change a path.

Why this site?

I’ve seen how badly I can misread the world when my body state is off: sleep deprivation can make neutral sounds feel like “disrespect”; in conflict my body freezes, my voice changes, and my mind races to justify why I’m right. Afterward I feel regret and shame, and then it repeats.

This isn’t rare. Many people know the feeling: you know you shouldn’t react like that, but you can’t stop; you think it’s a personality flaw, but often it’s a state problem.

From a psychology + neuroscience perspective, a few common mechanisms help explain it (understanding the direction is enough):

  • High stress weakens prefrontal function: when arousal is too high, inhibition, planning, and perspective-taking get worse; reactions become faster, harder, more extreme
  • The brain behaves like a prediction machine: we don’t only “see reality”; we predict based on past experience; under threat, predictions skew toward catastrophe and hostile interpretation
  • Emotion enters through the body: heart rate, muscle tension, breathing, stomach sensations often come before “I’m angry / I’m afraid” is even named
  • Patterns are circuits: repeated reactions are reinforced loops, not “who you are”; loops can often be rewritten, but they need the right sequence and small experiments

Starting in August 2025, I ran simple but sustainable self-experiments: track body responses, capture fleeting thoughts, and use AI to repeatedly unpack, compare, and review them. After three months, I felt something clearly: change is not about brute force—it’s about structure.

That’s why fixmd.io exists: to organize and share a structured path for people who are also struggling.

What’s inside?

  • Inner Work: real scenarios + reflection notes—you might read and think “this is me”
  • Tools: small games, tests, breathing and attention practices—turn insight into embodied training
  • Knowledge: clear explanations of how brain, body, emotion, and attention work together

A rebuilding framework I use

For me, “rebuilding” means: in the middle of pressure, I can pull myself back from autopilot into choice. The most stable sequence I’ve found is: physiology → cognition → action.

  • Physiology (lower arousal): bring the system out of threat mode (sleep, breathing, movement, rhythm, food); reduce the body alarm so the PFC can come back online
  • Cognition (defusion and reappraisal): separate “the voice in my head” from “facts”; when my PFC isn’t enough, use AI as an “external PFC” to name, layer, and untangle fused thoughts
  • Action (behavioral experiments): run small, tolerable experiments in real life; replace old scripts with real feedback; update default predictions with evidence like “I’m still safe / the relationship didn’t collapse”

I’m also exploring how AI agents can support the full loop so that “capture → unpack → practice → review” becomes lighter and more sustainable.

Who is this for?

Fixmd.io may be useful if you often:

  • overthink and replay in your head, especially under pressure
  • escalate in conflict, or freeze/people-please and then self-blame afterward
  • get hijacked by triggers (anger, fear, shame, anxiety) even when you “know better”
  • want an actionable path rather than slogans
  • are curious but cautious about AI, and want it as a tool—not an authority

A boundary

This site shares personal practices and tools; it doesn’t replace professional medical care or therapy. If you’re dealing with severe insomnia, depression, panic, trauma responses, or self-harm risk, please seek professional help first.
