What are the best candle scent families for creating a calming and relaxing atmosphere at home?

So I’ve been on this whole “make my apartment less chaotic” kick lately, and I swear candles are becoming my emotional support items. Thing is, I have no clue which scent families actually help you chill out instead of giving you a headache. I keep buying random ones and ending up with my place smelling like a fruit salad or a cleaning aisle. I’m aiming for calm, cozy, melt-into-the-couch vibes. If you’ve got go‑to scent families or combos that genuinely relax you, I’d love to hear them. My nerves (and wallet) need guidance.
