How to handle stress?

Stress is a common problem we have to face in our daily life. It's not something we can avoid and escape from. We all have those days that we feel overloaded and everything have become too much for us. For example, students may feel not ready yet for the coming exam; working professionals have hard time to meet deadline set by the boss; young parents are under both financial and mental pressure to raise children, etc. Some people may choose not face to the problems, but we have to keep in mind that problems won't go away until we find out a way to deal with them.
