Tonight I witnessed something violent and I dont know how to process.   

I am a manager at a fast food chain and when I say this place is hostile I mean its bad.  Ive seen employees without anxiety issues have panic attacks from the bs that goes on.  I have been keeping track of my anxiety attacks and I am up to 4 a night when I work.  Just driving to work is a trigger for me now.  

Tonight I had to call the cops on some employees.  They had taken a fellow coworker out back and ganged up on the poor guy.  I dont care what was said or how things started, no one deserves what they did to this guy.  It was three grown men against one and they werent just beating on him they were killing him. I  had to call the cops as i could not stop them ane would do it again and again everytime too.  After everything settled and the employee was taken to the hospital and police reports were done, I had to go back to finishing my closing shift.  As most of you know, after a hype comes the crash.  About 30 minutes later I could feel my breathing start to speed up and tried to do some breathing.  Thought it work but 10 mins later I got supper light headed and stopped being able to hear around me.  I was just stuck- this has never happened before.  
Now the image of the fight keeps coming back over and over.  Cant stop thinking about the evilness in my coworkers hearts and frankly not sure how im coming back tomorrow.  

I have a meeting with my supervisor tomorrow to discuss my options and hopefully can get a transfer. If not I dont know how to cope.  My family realize on my paycheck but I physical cant do it anymore.  Every shift is numerous panic attacks and when my coworkers notice what's happening its seen as me being weak and that really messes with my head.
