Mood swings can be caused by PMS and menopause . Right before your period every month, the levels of two hormones in your body, estrogen and progesterone, peak. This may cause depression and moodiness, which subsides when your period arrives and hormones fall to their lowest level. When you get to know your own cycle, you'll be able to predict when you're prone to crankiness, and this'll help you ride these days out.

Moods come in all different shapes and sizes.
Periods aren't always the cause. Job stress, family stress, growing up stress. All can add up to one very bad mood of colossal proportions. Most of the time, you can work these feelings out over time or over a hot fudge double deluxe ice cream sundae. Sometimes, though, things seem too depressing and hard to handle.
