Just curious, were you ever made fun of at school on an every day basis? Because unless you have, who are you to say whether it's worth it or not if you've never experienced that sort of pain? And even if you have, your ability to cope may be stronger due to biological reasons or the way you were raised. Some of these people are not only made fun of at school, but have also been degraded by their parents since they were kids, or have been abused, etc.
I'm not justifying suicide or arguing whether its wrong or right. But, I do try and empathize with people.
