What meds are you on? What is Klonopin and what does it do?
I had PND after my third child, but it was brought on by a severe episode of OCD focused around my teeth (too boring to go into).
Don't forget to take your meds. Don't beat yourself up on not doing your homework. It's hard to do anything when you've got a baby. Are you taking a good multivitamin, because pregnancy and breast feeding depletes your body of essential vitamins and minerals.
Accept that your thoughts are just thoughts. Just because we FEAR that we will do something doesn't mean we're going to do it.
As I said, my OCD during that time was terrible and I never harmed my baby. In fact he was a big, big comfort. He was the only thing that helped me relax.
But keep taking your meds and start taking a good multi if you're not already. Not getting enough vitamins and minerals can make your OCD and anxiety symptoms worse. Ask the pharmacist for something that's safe for breastfeeding, if you are breastfeeding.
Good luck and you'll get through it. Just make sure you look after yourself. Get enough sleep and make sure you eat properly. Motherhood, especially new motherhood, is very hard work. Don't try to be superwoman. Just take it easy and enjoy your baby.
