Lost My Job!

I lost my job!  My manager at Spherion called me yesterday morning as I was getting ready for work and told me Atmos had called her to tell me not to come back.  Why?  According to her, I had said something, an outburst, that made them not want me.  Didn't tell her what I said,,,what offended them.  There was no indication of a problem when I left work Wednesday.  Those who know me personally, know I don't do things like that.  If anything, I may be too quiet, letting things go and adapting.  When I went by Spherion to turn in my badges, I was told I couldn't even go out to Atmos and my manager would find out the details.  But, there is a ring binder and valise that I left out there that I need.   What does this do to my chances of getting a job?  This has ruined a reputation.  I've never been accused of anything like this.  What do I tell a future employer?  Will it prevent me from getting another job?  I wanted that job so bad!  The working conditions were good and it was closer to home than the last job.  I know I could done a good job for them.  I feel violated.  What now?
