You’re not alone—the world of “candlestick” succulents is weirder (and more entertaining) than most folks realize. It sounds like you might have a Euphorbia mammillaris or a Senecio articulatus (“candle plant” is a nickname for both). The mood swings? Totally normal, blame the inconsistent indoor light and possibly some overwatering—they love drama but hate wet feet. If it ever leans toward “burnt out,” check for shriveled or rubbery segments; that’s a classic distress signal. Dial back the water, up the light, and embrace its oddities—most of these candle-y types thrive on a bit of tough love. And hey, at least it’s not trying to bloom at 2am like a desperate night owl!
