I AM USELESS

i followed this guy on tumblr, she's a role player just like me and then last few days she told her followers to help this girl who wants to commit suicide and so i followed the girl and talked her out of it. i don't think it was just me, there a lot of other people who talked to her and she said she'll try. she been posting very emo stuff on tumblr lately and just now she put up a post saying she wants to kill herself and then she deleted it! I got so scared! I went to mail her and tell everything i could so she'd change her mind, she responded at first and then she stop responding! I AM SCARED NOW. WORRIED SICK. I asked my other tumblr friends to help convince this girl and they all say she isn't responding! WHY! I am scared right now :( I couldn't help her! WHY?! YER UGH NGAI!
