Faculty Evaluations of Institution

I'm faculty and I work at a place that does faculty evaluations of our institution. I wrote a pretty harsh, but true comment on the back. While it's supposed to be anonymous, I'm still afraid it could be traced back to me. I know, it was a dumb move, but it didn't occur to me that writing the comment would be. Do you think I will lose my job over it? Maybe another dumb question, but I'm stressing right now.
