Aw, Crystal. I feel so bad - I know how it feels to be threatened on the internet/cyberbullied. I actually still am, but that's beside the point. I have been there, the lowest point in my life, the feeling that there is nothing left, the feeling that is just terrible. It consumes your mind, it makes you feel like that is normal. I still visit the God darn place once in a while, but I try to avoid it as best I can - even if it doesn't work out the way I planned.
As for the bullying, please tell someone, it doesn't matter who they are or where they are. Report them, block them, anything to get them ignored.
It's good you're writing it - a wondeful coping skill.
Also, if you ever need to talk to someone, you may PM me.
Stay strong, dearie~
