- People describe mood swings as emotional transitions that feel disproportionate to circumstances — shifting from contentment to tears, from calm to anger, or from energy to flatness without a clear external trigger. The unpredictability is often more distressing than any single emotional state: not knowing what the next hour will bring, feeling out of control of one's own emotional landscape, and the relational strain of others having to navigate the volatility. Some describe their mood swings as physically felt — a hormonal surge, a tide-like quality — while others experience them as purely psychological. Many describe significant shame and self-criticism after the shift passes, wondering why they 'can't just be normal'.
