Even if CoasterCrazy isn't a community that you feel welcomed in or wish to participate with, know that taking your life is not worth it. I'm assuming that you're younger in age. You have your whole life ahead of you. Just because things may suck now, whether that's school, home life, or whatever doesn't mean it can't get better.
If you need some one to talk to, there are a number of professionals you can reach out to through a multitude of ways through
http://www.suicidepreventionlifeline.org/ or many others like it.
Some where, somebody out there cares about you and it's not fair to them and it's not fair to yourself. Perhaps taking a break from CC might be good for now. Just take a break, and when you feel like you're ready come on back. Or as the admins have offered, they are also there to talk to you too
- edit - I just noticed I'm a month late, but regardless there are probably many others who might wander onto this post who feel the same way. I think the help and suggestions offered here and throughout the thread are still relevant.
