Any of you got anxiety AFTER you had a baby?? I was watching kardashians and Kim said she never had anxiety before and she always think of these horrible scenarios. So the therapist was saying it maybe passing anxiety because when you have a child you're taking on so much responsibility and it can be overwhelming... I'm trying to find the correct terminology for this so I can google this because I think I may have this. I have never had anxiety a day in my life until my baby was born. Any ideas or any other moms go thru this and how do you handle it?
