What can I do for this type of anxiety?

See my signature for my journey so far.  Over a month ago, I drank a few nights in a row and sent myself into a massive wave.  During this time I took a couple rescue doses of klonapin.  I’m not doing that anymore. 

I’ve been waiting for this wave to subside but it’s getting worse.  Almost everything I do causes me to be over stimulated and my heart to pound and my chest tightens up.  Then my stomach will start making noises.  Nighttime is horrible, I can’t sleep for a lot of the night and wake up in a panic.  I’ve tried Unisom to help me sleep and can get a couple hours but that is it.

Has anyone felt like this before?  How do I get through this?  I’ve been giving it time but it’s getting worse.  This isn’t even in my taper so I can’t see an end.
