As Kragshot said, real-life problems make much better trouble aspects. And they don't have to sound mundane, either. You just have to figure out how to word it. For example, my character is a man who keeps a nearly uncontrollable rage bottled up inside. It's just really, really bad anger issues, but Anger Issues isn't a very interesting aspect name, so instead I named it The Beast Within. That says the same thing, but also represents how he fears the anger inside him and how much damage it can do to people that are nearby when he lets the monster out.
