5. Grumpy All the Time?
Snapped at your co-worker? He may have had it coming. But, if you find yourself having a hard time relating to your family, colleagues, and friends, it may be a sign that your emotional moodiness is too much for you to handle. Being down or depressed is a physical and emotional energy suck, Rock says. It takes all your energy to get through the day, leaving little for self-restraint when it comes to speaking your mind.
Again, it’s likely not full-blown SAD unless your crankiness is interfering with work or your personal relationships—or if you notice it along with several other symptoms, Rock says.
