If it's wrecking your life, it's probably SAD

The difference is severity and duration, not just feeling a bit down in February.

Winter blues are annoying but manageable. You feel low energy, crave carbs, sleep a little more. But you still get out of bed, go to work, hang out with people. It lifts when the sun comes back. SAD (Seasonal Affective Disorder) is clinical depression with a seasonal pattern. You’re not just sluggish—you’re struggling. Hypersomnia where you sleep 10+ hours and still feel exhausted. Carbohydrate cravings that feel compulsive. Loss of interest in things you usually enjoy. Trouble concentrating, withdrawing from relationships, feeling hopeless.

The key difference isn’t what you feel—it’s whether it impairs your life. If you can’t function normally for weeks, that’s SAD. If you’re just grumpy and tired, that’s winter blues. Also, SAD symptoms typically resolve fully in spring, while winter blues tend to fade gradually. For a formal diagnosis, the pattern needs to show up for at least two consecutive winters.

If you’re honestly asking “is this more than normal?"—it probably is. Track your mood and sleep for a week or two, then decide if it’s worth talking to someone.
