Think about your day and every moment of trust you must have: it's quite astounding. You must trust your alarm clock will go off, trust your car will start, and trust the people around you. It's true, some elements of the day hold more trust than others, but nonetheless they all involve the same need to trust.
I look around at the people who influence my life every day and I am truly grateful. My days are surrounded by so many wonderful people. I trust them with my life, both literally and figuratively.
We all have them to some extent, mine just seem to be primarily with myself. I do not trust my body and I certainly do not trust CF. It would be fair to say that CF has robbed me of certainty within myself: it continually asserts its strength, and it terrifies me to think of its destructive ability both physically and mentally.
