I have been really moody lately and i feel like i'm depressed. how do i go about checking if i am or not. it's been a year after i've had my first kid?

Impairment and mood: Basically a depression is a period of persistently pessimistic or negative mood associated with certain symptoms (appetite, sleep, energy, etcetera) that causes impairment in function and not due to a medical condition, a drug or other non-psychiatric cause. You could take the screening questionnaire from the mental health association - http://www.Mentalhealthamerica.Net. See your doctor.
