Postpartum Anxiety

Does anyone emsuffer from postpartum anxiety. I've been pregnant twice and both times have suffered terribly from anxiety I mean full blown panic attacks that send me to the Er it causes me tachycardia and alot of physical symptoms. It seemed like the second time was worse then the first and it lingered longer it stayed for like 9 months of suffered it gets better though. Like it does not go away completely but it gets to the point that it's manageable. I'm terrified for this my 3rd pregnancy but the postpartum 😔 The thing is that I don't even start suffering from it until my babies are like 4 months or older it's so hard on me.
