Postnatal Depression is what happens when you become depressed after having a baby. There may be an obvious reason, but often there is none. It can be particularly distressing when you have looked forward to having your baby through the months of pregnancy. You may feel guilty for feeling like this or even feel that you can’t cope with being a mother. It can last for weeks or several months. Mild PND can be helped by increased support from family and friends. More severed PND will need help from you GP, health visitor or, in some cases, mental health professionals. Around 1 in every 10 women had PND after having a baby. Without treatment it can last for months or rarely, years.
