It's basically talking about people who cute their wrist. I personally think by the way they sarcastically say "you think the whole world's against you it's never your fault we're the ones with the issues", is saying you're using it as a way of getting out the problems you have. But when somebody has a problem, it was usually caused because of something they did. Cutting your wrist is a easy way out of fixing stuff.
