I had prenatal panic disorder in all 3 pregnancies to varying degrees in each one.
But after the birth of my 3rd baby I also had PostNatal Panic Disorder. It was awful and completely debilitating. It lasted approximately 12 weeks.
I didn't even know it was a 'thing' until I did some reading on it some time after I had got better.
Ask me anything and I will do my best to answer to the best of my knowledge.
