Do I have a problem?

The Extremes I've gone through in the past two days:

Complete Hopelessness <-----> Neverending Possibilities

HATE for Plan B. <-----> Complete Indifference for Plan B.

Despair <-----> Ecstasy

Desperately Sobbing <-----> Hysterically Laughing

Is this what life is all about?? Learning how to stay between the extremes? I need HELP.
