Beckylynn,
Keep that positive attitude. Remind yourself of your reasons for quitting and all of the benefits of quitting; health, financial, physicals, etc... Check out our sister site at DepressionCenter.net if you continue to feel a little bit down. It's normal to feel depressed after you've quit as nicotine stimulates the 'feel good' receptors in your body. To help get this feeling back try to engage in pleasurable activities and exercise to increase your heart rate.
If these feelings continue or worsen, we suggest that you consult your doctor.
