What Should I Do If I'm Depressed During My Pregnancy?
Preparing for a new baby is a lot of hard work, but your health should come first. So, resist the urge to get everything done -- cut down on your chores and do those things that will help you to relax. Taking care of yourself is an essential part of taking care of your unborn child.
Talking about the things that concern you is also very important. Talk to your friends, your partner, your family. If you ask for support, you'll find that you often get it. If you're still feeling down and anxious, consider seeking therapy with a mental health specialist.
Evidence suggests that many antidepressant medicines are safe for treating depression during pregnancy, and will not harm your growing baby -- at least in the short term. Long-term effects have not been properly studied. You should discuss the possible risks and benefits of antidepressant medication with your health care provider. If necessary, he or she should also be able to refer you to a mental health specialist.
