I started talking to someone new and I'm concerned for them

Their life doesn't seem great right now, and while I'm happy to listen and give advice where needed, it's starting to feel like we're going in circles a bit. They talk about the same thing repeatedly even when I ask them questions to try to get a better understanding of what's going on, and they're clearly unhappy but it seems like I can't get through to them that maybe reevaluating things is necessary. I want to help but it seems like there's nothing I can do.

I guess I'm just worried. They seem like a realy nice person and I think I'd like being their friend in future. But for now I'm worried about them.
