When you say they took you off Paxil, did they take you off it suddenly? Did they taper? What you're suffering sounds like Paxil withdrawal as much as it sounds like a worsening of your anxiety. And as far as how long panic attacks, which are the same thing as anxiety attacks, last, that totally depends on the situation and the person. Although the most intense anxiety only lasts a while, anxiety can remain elevated for hours afterward. Have you ever had talk therapy so you can understand your condition better?
Anxiety can often become intensified when a little one is on the way in my opinion. Even though, I seem to be more of a mess than my wife is when she is pregnant:). First of all, you are not going crazy; second do you have access to a counselor to talk this through? I find the best tool to use in confronting and dealing with this is knowledge of the condition. Sometimes being able to get this off of our chests is a huge release and as an added bonus, we learn how to live with this....keep us posted!
