Life can be stressful without putting CF into the mix. I have days that it scares me that I am so sad. My brain knows I shouldnt be because all things considered I am very fortunate for the life I have yet there is that part that gets stuck. Fortunately for me it always passes. Sometimes it comes from lack of sleep, lack of fun, my period or even the weather. Do the best that you can in taking care of not just your kids, but yourself. Things will improve! Hand in There!
