Fear

Paranoia is miserable. What's worse is to fight fear with apathy, because they both end up putting a lot of distance between you and the world. They keep people caged into depressing little cycles that won't let them move on and try new things and really live life the way it was meant to be lived. I've had a lot of experience with apathy, and a recent run-in with paranoia, and I think it's safe to say that I'm going to make a conscious effort to keep them out of my life, or at least understand where they come from so I can move beyond them.
