honey, the world may seem like it's full of wackos who just want to hurt you, but it's twice as full of people who care, who want to help others. People aren't half bad- hell, they're not a quarter bad. I think maybe you know that at least a little bit- otherwise you wouldn't have asked complete strangers for help.
Firstly, you are not alone. i know exactly what you're going through, having started at the same age and having felt the same way you described. I started when i was 12 and i haven't done it again since i was 15. (i'm 17 now.)
Secondly, if i can stop anyone can.
you're not broken, nobody needs to fix you. you just need to realize your infinite potential and enormous worth. you're a beautiful individual and you DO NOT deserve to be hurt, by anyone in the world INCLUDING and especially yourself. please message me any time i feel like it- you can't freak me out and i won't think less of you no matter what. so vent, chat, rant, ask, whatever. just know that there are people in the world who want to help and honey I'm one of 'em!
