When Fall Changes Your Mood: Bipolar Disorder and Seasonal Depression

The other day, I was walking the dogs with my wife, when I felt the change in season in my body. Cool air, cloudy skies, and a strange wave of slowness. I tried to explain it to her as we walked.

If fall brings a shift in your energy, sleep, or mood, you may recognize that feeling.

In this episode of The Bipolar Bro, I discuss bipolar disorder, seasonal depression, and how I’m preparing for the transition from summer to fall. Drawing on my experience living with bipolar disorder and my background in exercise and nutrition science, I explore what the research supports, where the evidence has limits, and how to turn familiar advice into a workable routine.

I also share why I’ve been quieter lately. This spring, I’ll begin studying part-time toward a Master of Divinity at Midwestern Baptist Theological Seminary while continuing to work full-time, invest in my marriage, and think with Sarah about growing our family.

That decision brings up some honest questions about faith and disagreement. I explain my egalitarian convictions, why I admire my wife’s leadership, and how women such as Deborah, Huldah, Priscilla, Phoebe, and Junia shape my understanding of Scripture. I also discuss why I want an education that challenges my thinking.

In this episode:

* Seasonal mood changes: What I noticed on that walk, and why one difficult afternoon doesn’t establish a diagnosis.

* Daylight and bright light therapy: How they differ, and why light-box treatment requires particular care with bipolar disorder.

* Sleep and exercise: Protecting a consistent routine, choosing manageable workouts, and allowing recovery.

* Nutrition and connection: Making meals easier when energy drops and staying in touch when withdrawing feels tempting.

* A practical fall plan: An adaptable example week, a brief sleep-and-mood check, and a simpler approach for low-energy days.

* Faith, marriage, and seminary: Learning through disagreement, supporting women’s leadership, and making room for a busy family life.

I close with a short prayer and a request for prayer for Sarah and me as we prepare for the months ahead.

Whether you’re Christian, questioning, or don’t share my faith, you’re welcome here.

A question for you: What tends to change first as the days get shorter: your sleep, energy, motivation, or desire to see people? What has helped you respond?

If this conversation brings someone to mind, consider sharing it with them.
