I have not been in law enforcement, but I was in a highly stressful work situation for quite some time and I did develop some issues. I did not have anxiety attacks or anxiety issues outside of work, but my body got into a pattern where as soon as I pulled into the parking lot the symptoms would start up again, as if in anticipation of the triggers that came all too often. It was really miserable and ended up causing stomach pain after it went on for so long. Things were resolved and I was able to recover, but it was a really difficult year for me. I can imagine this kind of thing does and has happened to many cops, especially if they have to work in an part of town where there is a lot of tension and crime for a lengthy period of time.
