I just opened a new claim for intermittent FMLA. Usually it's IBS symptoms that get aggravated my my MI. And yes, I do feel guilty for using it, but that is what it is there for. I don't want to use it, but this time I need to act on it fast so that it doesn't get REALLY bad like before, when I was using it all the time and going out on short-term disability for a month or two at a time.
