Life changes on a dime. One minute everything is looking up; all the cogs are turning; everyone is healthy and happy. Life is good. In a moment, that can all change. Someone becomes ill; someone dies; a job is lost; a factory closes down; the house catches on fire; the car breaks down; or floodwaters rise. Our world spins all topsy-turvy. The way things were suddenly seems like a dream as our present reality becomes a nightmare.
Some people can be caught off-guard by a life-altering incident, but they have the ability to see past the event and understand that, while life may not be the same as it once was, it will be good again. We plod along through the mire and muck until we can see a bright spot to focus on. Things get better and we move on.
For others, it seems like one bad thing leads to another, and then another, and so on. Its almost like nothing good is ever going to happen. When something good does happen, its so random and fleeting that it doesnt even seem real.
