Congrats on your new baby! I'm so sorry you have to go through PPD in what should be a happy time. It's not easy, and I feel for you. Treatment is a personal thing, as we all are different and respond to different remedies. The most important thing to know is that you are not alone, and you can get better. You may need try a couple things working with your trusted doctor/midwife to find what works for you. Studies (according to doctors) have shown that medication is the quickest route to getting some kind of relief from symptoms, but many doctors also recommend additionally to use group therapy, individual talk therapy, seeking support from a partner, or family/friend, etc. which will also help you on the road to recovery. Don't be afraid to reach out--you need all the help you can get right now, and that's OK.
I took prozac, but after I had already undergone other treatment and learned about my specific condition, as mentioned in the article.
Your recovery will not happen overnight, but just think that all you have to do is get through today, and then tommorow get through that. Be confident that if you are doing something positive about it, you WILL get through PPD. Be happy for every little thing you accomplish (ex., taking care of baby, taking a shower) and let go of some things. For example, if you didn't get a portion of your 'to do' list done today, don't beat yourself up. Before you know it, it will be longer and longer between experiencing symptoms, and you'll be well on your way and back on track! Please let me know how you progress in your journey.
