1. Seek Professional Help
Getting medical attention is the first line of defense against postpartum depression. Your provider should be screening you using a series of questions at all your postpartum appointments. You'll be asked to rate yourself according to various statements regarding how you've felt in the past seven days, such as, "I have been so unhappy that I have been crying." 

If you suspect PPD, your personal doctor, OB, midwife, or child's pediatrician can all help you or get you to the person who can. You can expect to be evaluated and issued a plan of treatment moving forward. Sometimes just knowing that you're doing something about it can make you feel better.
