I find it far too easy to become completely overwhelmed by fear. Difficult situations, well, they're difficult for me to handle and sometimes it takes me a few tries to get my head in a reasonable state to do what needs to be done.
There are some things that are so important, that no matter how difficult they are, or may get.. it's impossible to give up on them. Giving up isn't even an option, and if it were, it wouldn't even be considered.
When you lose something important, it's then that you realize just how much that something meant to you. And even though you already knew that it was special, you see more clearly that there was even more than that. To get another chance is rare, but to get another chance and lose the most important thing in your life again – well, that's just not gonna happen.
