anxiety/panic attacks

Anyone else experiencing extreme anxiety or panic attacks while pregnant? This is my third pregnancy. I miscarried last June, and I have a 3 year old. I've never experienced anxiety with either of the other pregnancies. I am having attacks almost daily and sometimes more than once a day. It really sucks. I'm still trying to figure out what works for me, and how to accept what is happening & that it WILL go away. I often feel like what's happening isn't real, it's hard to explain. I feel crazy!!!!
