Some claim that you don't see a person's true colors until you start planning your wedding. Most of the time dealing with all of the personalities is much harder than dealing with the actual planning itself. For some reason, I've found that weddings have a way of turning even the most mild-mannered, normal human beings into Gary Busey.
You've all seen the movie Bridesmaids. The tea party bridal shower with the giant cookie, and Kristen Wiig's meltdown scene is the thing that sticks with me the most. Weddings can get extremely stressful for the wedding party, since a lot of the responsibility in making the bride feel special rests on them.
The subsequent years can bring childbirth, raising children, and your kids departing for college, leaving you feeling lonely. Some adults find they are single again later in life. Life is full of changes. We need to learn the coping skills so food does not become your companion during sad, stressful, or happy times, and alcohol does not become your self-confidence.
