To treat postpartum depression, it's essential to talk to your primary care provider or a mental health professional, as opposed to simply "waiting out" your feelings.
A doctor can monitor your symptoms, give you a diagnosis, provide you with a safe place to talk about your feelings, and help you find a treatment plan that works to alleviate your symptoms. For some mothers, a weekly therapy session can help them work through their feelings, solve problems, and learn to cope with stress and anxiety.
For other mothers, antidepressants or other medication may be a great option. Though any medication you take while breastfeeding will enter your breast milk, there are many antidepressants that are safe for both moms and newborns. Even after you begin to feel better, continuing treatment can help to prevent PPD from becoming chronic depression or anxiety.
If you think that you may be at risk for developing postpartum depression, talk to your doctor about any concerns you have before giving birth. This way, both you and your doctor can prepare yourselves and keep a close eye on any symptoms that may develop.
