Swings can be challenging. One week you can feel hyped up, capable of accomplishing a great deal and you don't see a reason to stop. You feel like you are on a roll, but everyone else is too slow.  You may say or do things at the spur of the moment, things you may later feel embarrassed about. The next week you experience a long period when you lose all that energy and you are unable to experience any pleasure or satisfaction in anything you do.

You can lose your self-confidence, and even feel like you have no significant reason to live. These shifts in your mood can make you angry, irritable, and short-tempered, affecting your relationships, your job and your self-esteem.
