Klonopin vs ativan?

I had a severe panic attack a month ago and called 911 from the highway because I thought I was having a heart attack.  Since then I now have frequent panic attacks and anxiety.  My anxiety seems to bread more anxiety and now I worry that it's making me crazy.  what a horrible feeling.  I was taking ativan and now my doc. has switched me to klonopin.  Have people had more success with Klonopin?

Klonopin is usually prescribed more long term because of its longer half life.  Both do a good job in what they are designed to do in my opinion, but ativan is usually prescribed in the short term.  During all of this, have you made arrangements for counseling?  Learning about your panic is a great way to confront it, understand it, and ultimately beat it in my opinion.
