Overfunctioning / Underfunctioning/OH-ver-FUNK-shun-ing / UN-der-FUNK-shun-ing/
Two common responses to stress: doing "too much" (taking on everything, over‑controlling) or "shutting down" (reduced capacity, withdrawal).

Andy says:
Like flooring the gas vs. stalling the engine—both signs the car needs a pit stop, not blame.
Detailed Explanation
Overfunctioning can look like hyper‑productivity, caretaking others, or perfectionism. Underfunctioning may mean reduced initiation, more rest, and opting out. People can swing between the two. Supports aim for co‑regulation, boundaries, and pacing.
Community Context
In ND spaces, these patterns often reflect energy, sensory, and executive load—not character. Shame fuels swings; structure stabilizes.
Quick Tips
- Name which mode you’re in; pick one stabilizer (rest, boundary, checklist)
- Cancel non‑essentials; ask for help
- Use energy budgeting to return to mid‑range
Do / Don't
- Do: reduce demands; build small wins
- Don't: moralize productivity or shutdowns
Scientific Context
Stress/arousal models explain shifts in capacity; regulation and environmental changes improve functioning.
