I personally told everyone I directly work with about me having CF, and even though they know, they will never truly understand. They might say they understand it, but you never truly know what one goes through until you have walked in their shoes. For instance, I am trying to go mostly dairy-free, but I cheated last night and had a cheese pizza. Well needless to say, I literally paid the price for my deviating from my self-imposed diet; I had severe stomach pains and threw up about every 2 hours. (It was probably a combination of that and catching a stomach bug, cause someone at my work was sick)I could not get up; I was accurately placed in the fetal position all day long and could not catch even a minute of sleep last night. Hence, I am dosing myself with Tylenol with Coedine, and it seems to be working fine. Now I called off today, but this is an anomaly for me as I almost never call out. I'm certain that if anyone at my job experienced the same pain sensations that I had they would have gone to the ER in a heartbeat. It boggles my mind how people complain of a little headache or muscle ache or call off due to them stubbing their toe when in reality pain has a leading role in my life.
