I downloaded every app and still felt like a failure

There was a stretch of my life where I tried to fix myself with apps. I downloaded every productivity tool I could find while my body was running on empty. I felt like a failure, over and over, until it clicked that I was not lazy. I was fighting my own biology.

That is the whole reason this conversation hit me so hard. My guest this week, Rhiannon Neuharth, helped me understand why all the planners and supplements in the world fall flat when your body is stuck in fight or flight mode. If you have ever felt foggy, tired, and behind no matter how hard you push, this one is for you.

Meet Rhiannon Neuharth

Rhiannon is a former anatomy, physiology, and biology teacher who also worked in a genetics lab before she became a health coach. She helps burnt-out women understand their bodies using their genes as a kind of blueprint. Her shift from the classroom to coaching started with her own daughter’s long health journey.

You can find her work and grab her free MTHFR 101 guide, her ADHD Brain Food mini course, and her comprehensive testing options over on her website, Revitalizing Wellness. She also breaks down a ton of this for free on TikTok and Instagram.

Why your nervous system has to come first

Here is the part that reframed everything for me. Rhiannon put it simply. If your body is stuck in fight or flight, she could hand you every supplement and every diet, and you still would not absorb any of it. Your body is in survival mode and is doing the bare minimum to keep you going.

So before you blame yourself for not sticking to a routine, look at your baseline. A dysregulated nervous system shuts down the higher level thinking that planners and habit trackers depend on. As she said, your genes can load the gun, but your environment and your stress pull the trigger.

This matters even more after burnout. Once you hit ADHD burnout, no planner is going to save the day. The first job is getting back to a calmer baseline, often with the help of a community that can step in when your capacity is low.

What MTHFR actually does

A lot of people hear MTHFR and panic. Rhiannon keeps it grounded. The MTHFR gene is like one cog in a much bigger wheel. When that cog is chipped, a process called methylation does not run smoothly, and your body can struggle to detox and process certain nutrients. That can show up as brain fog and fatigue.

Methylation touches around 200 processes in the body, which is why MTHFR symptoms can feel so scattered. If you want the science straight from a trusted source, the National Library of Medicine’s MedlinePlus page on the MTHFR gene lays out the basics in plain language.

One honest takeaway from Rhiannon stuck with me. Even though influencers push methylated vitamins for everyone, those are not right for every body. That is exactly why she is such a fan of testing instead of guessing.

Your gut is your second brain

We also got into food. Rhiannon calls the gut your second brain, and the science backs the idea that your gut and brain are in constant two way conversation. Johns Hopkins Medicine explains this brain gut connection and how gut trouble can stir up mood and focus issues.

She shared a powerful family story. Her son was acting out in ways no one could explain, until food sensitivity testing showed he was reacting to certain foods. Within a week of removing them, he was calmer and more himself. That does not cure ADHD, and she is careful to say so, but it can bring the body back toward a baseline where everything else works better.

For more on the genetic side of attention and focus, the nonprofit CHADD is a solid, evidence based starting point.

People Also Ask

Q: What does the MTHFR gene do? A: It helps your body process folate and run methylation, a process tied to detox and nutrient use. A variation can slow that down and may contribute to brain fog and fatigue.

Q: How do I get out of survival mode? A: Start by lowering the load on your nervous system before adding new tools. Rest, support from people you trust, and small calming routines help your body leave fight or flight.

Q: Can supplements fix ADHD symptoms on their own? A: Not really. If your nervous system is dysregulated, your body may not absorb or use them well. Regulation tends to come first, then targeted support.

Your one next step

If you take one thing from this episode, let it be this. You can stop chasing and start understanding. Pick one small calming habit, then look into testing so you are working with real information about your body instead of guesswork. Rhiannon’s free MTHFR 101 guide is a gentle place to begin.
