Tw: Heavy topics like s*icid$ and trauma

Im not feeling like a poet today so I won't be making a huge text But I have this friend I met online, they told me they want 2 kill themselves in a specific day next year, idk what to do, Ive known them for just 1-2 months but I feel attached already, and if I didn't, I would be concerned too They have a really dark past, I don't know many details all I know it's fucked up and they been going through a lot since then, I don't feel panicked yet but I feel like I might cry at some point All I could say when I found out is that I would be by their side always and asked them if they tought about what they might miss if they're gone, they didn't respond but ik they read my messages bc they reached w a little emoji What do I do? Pls, I need advice, im getting scared, this never happened 2 be before..
