Stress, social isolation, sleep deprivation, and deviation from your normal routine can trigger episodes of depression or mania. Be cautious during life changes like starting a new job, going to college, or getting a divorce.
Also be aware that you can encounter problems even when it’s not a major event. “It doesn’t have to be a fight or a major disruption in your day,” Hoepner says. “Anytime you are out of balance, it can be a trigger.”
