My only friend in the world has been texting me about "going on a trip" alone and just now he's saying "its the kind of trip you dont come back from". A week or so ago he said he was "running away" (he's 22 and I'm 21) because he didnt feel like himself. Now hes saying today that he's going on a road trip by himself and not coming back.

I'm really scared that he's going to kill himself. He's joked about it before but that was blatant "Welp, gonna go hang myself" type shit but how he's avoiding saying the word and he's being secretive and cryptic about it I'm really genuinely worried this time. The last few months hes been saying how he thinks he's manic depressive and how he doesn't feel like himself anymore.

What do I do? Seriously, he's one of my only friends and I dont want to lose him to this stupid bullshit. I don't want to call the police or his family or anything and risk embarrassing him and pushing him over the edge but I think I'm the only one who knows and I know he'd hate if it got out to anyone else. I just don't want to fucking lose another friend what the fuck do i do.
