If you are unhappy at work you have a few options.
Quit right now with no notice, telling them to take the job and shove it as you walk out the door. Feel a few moments joy and freedom until you take yourself to your next money making opportunity (if you can find one) and, most likely, recreate the same unhappiness you had before.
Stay with a bad attitude. Tell the story everyday of how you hate your job, the people you work with, and how you are underpaid, underappreciated, and have no options. The more you practice this outlook the easier it becomes.
Stay and tell a different story. Talk about what you appreciate about your job or career. Practice looking at the bright side and you will see more bright side. Heck, your co-workers and boss might even start treating you differently.
* Stay and tell a different story while defining what you want in your next career move. Be on the lookout for the next opportunity all the while appreciating your current position and building more skill and contacts.
