my friend went missing and i can't do anything

i feel bad that i couldn't do anything to save them they might already be dead or maybe still missing. i hesitated to tell everyone because nobody would listen to me, plus I'm too much of a coward to even speak about them because i was afraid they would hate me.

their sister hasn't replied to my messages for news about them, I've tried calling a few times and there's nothing. my friend has been missing for a month. I don't want to accept that they're dead. i really wish i could help with atleast anything, i just want to know that they're safe. why are you so stupid didn't i tell you not to kill yourself again??? please don't die atleast just stay safe I'm here for you even though i don't even know you at all I don't care what you do or what you did please tell me what was troubling you so i could help you don't be so stupid
