I've lived with anxiety for most of my life, though I didn't know that until I was an adult. However, thanks to years of experience and lots of therapy, I figured out how to live my life without too much difficulty; until I got pregnant. Between the hormones and all the worries that come along with bringing a new person into the world, I basically had to start all over when it came to figuring out how to deal with my anxiety. Motherhood can make a woman's anxiety worse, but there are definitely ways to cope.
It's important to note that parenthood can make everyone feel anxious or worried at times, but there is a difference between experiencing normal worry and having an anxiety disorder. For instance, it's common for new moms to be worried about their new baby's breathing. It's not normal to forfeit sleep so you can stare at your newborn all night to make sure their chest continues to rise and fall, like I sometimes would. It's normal to be concerned about the baby being around sick people. It's not normal to avoid leaving the house for days on end because you're worried someone might cough near him on the train.
When your worries start causing you physical distress and/or interfere with your ability to eat, sleep, and function throughout the day, you need to get help. Personally, I manage with talk therapy, talking to friends and family who get it, making sure I eat well and exercise, and getting enough sleep. Some folks also use medication in order to get relief, which is a totally valid and important part of treatment that moms shouldn't be afraid of pursuing (or admitting to using, if they feel comfortable speaking about their medical history with others).
If you're finding that the following aspects of motherhood are becoming too much for you to handle on your own, know that you are totally not alone. Talk to someone about it and figure out what you need to feel better. You deserve to live your best life.
