bro, I had a serious heart concern which caused me major anxiety. I got prescribed xannies and klonopin. I would stay away from klonopin.....and only take the xannies when you ABSOLUTELY have to. You're probably not sleeping well are you? When you're not sleeping right your brain isn't healing itself and that can cause some serious nuerological problems that result in anxiety and/or depression. I can only state my own experience, Klonopin gave me a feeling of breaking from reality, best I can describe it.......and it happened while driving, so that was it for me. These are very powerful drugs that many times come with another set of side effects. Avoid them if at all possible. I understand anxiety bro, so I know it's just not that simple. If you want to talk via PM I'll go into more detail on how I personally dealt with it.
