I'm the same way ... every little thing out of the ordinary sets me off. I don't know why. A couple years ago just before I retired from my job I went to the Dr. because I was starting to have physical sypmtoms of stress and nervousness....didn't know that's what it was at the time. She put me on a very low dose of anti-anxiety medication and that has helped some. But I still get nervous and anxious about really stupid things.
