Watching someone you love go through difficult times is like being trapped in your own body but paralyzed. You want to yell at them, scream, help them, but your body won't move, and you know that no matter how hard you try, in the end, the path is theirs to choose. You can't choose for them. What a terrifying concept, especially considering we hardly see every option when we're stuck in our own self-defeat.
It's a little convenient, isn't it, to say that the reason you did something horrible was because someone else told you to. That doesn't make it any less wrong. No matter how many people are telling you to jump off a bridge, you always have the option to turn around and walk away.
