your biggest fears

As a parent, I honestly have to say my greatest fear is failing my daughters as a good father. I have phobias, certainly, things I don't like, give me the chills, make we want to throw up and such. Perhaps its instinctive, but theres a part of me that doesn't want to allow anything bad to happen to them, and then the logical where I know bad things will happen to them. However, I'm not certain I can trust myself to react wisely if something severe were to happen and there is a great fear in that thought alone.
