Can only talk about myself, so please take this and any other advice with a grain of salt. Every person is different and reacts differently to this.

The headspace he’s in right now is one of utter confusion and emptiness. For now the dread might be gone. But he is probably far from ok. What he needs right now is love. And I don’t mean hugs and kisses and shit.

Let me explain it this way: He needs normality in a cozy environment. Friends or family around him to have idk like a pizza together while playing games or watching something he’s interested in. The important part is that they are there in person and not everything revolves around him, but with him. If that makes sense?

He doesn’t need an intervention kind of “we love you” bs, which to me sounds like hell on earth. He needs to live the love. Cherish others while being cherished.

I hope my word salad helps. Sorry I woke up two hours too early and my brain is still trying its best booting up.

People talk about being there "for" someone. Here being there "with" him is more important. Something as mundane as letting him take a nap on your couch while you fold laundry. The more regular, boring or routine the better. Best if it's something you can do without talking. That's harder since you can't go see each other, but maybe just leaving a video call on or suggesting it to someone else would help.

Reach out to family or friends or anyone who can be with them now.

Call one of the suicide crisis numbers for your country and talk with them. Even though it is for someone else they will be able to help you try to get your friend help.

One of my closest friends tried attempted suicide last year. The first thing obviously was to make sure he survived. We don't live in the same city, so that was a very long and stressful day for me. Fortunately, we have mutual friends who I could reach. (I was the only one he texted before the attempt.)

Anyway, after he was well, I never really pressured him to talk about it. I, and others, convinced him to talk to a therapist. After I believe a week or so, he just randomly opened up and we talked for hours. This happened a few times. But I always tried to not pressure him into opening up, and kept our friendly banter and everything. I never wanted him to feel that something between us changed because he tried to take that route. I'll still call him names and roast him, and he'll clap back. That's just our dynamic. I think people often overcompensate, and end up making things worse.

That paragraph turned out to be much less structured than I had hoped. It's just hard to put into words what to do. I guess, just try to be a good friend. Whatever that means for you. Be there for them. Talk to them. Don't pressure or guilt them into doing anything. Don't guilt yourself into behaving differently. Be compassionate if they do open up, but don't force them. Just be like you usually are, grab a drink maybe, and have a good time with them.

Probably take them to a hospital
