Someone you care about is in a dark stretch. Here's how to be useful without making it worse — and how not to burn yourself out doing it.
An initiation ceremony from around 1888 had one line for the person who walks ahead of someone blindfolded:
The Kerux is the one who carries the lamp. Two things worth taking from that: the job is to go a little ahead with a light, not to carry the person. And they may not see it while it's happening. You do it anyway.
Most help goes wrong because the helper guesses. Ask, in these words:
Then do that one. If they say "heard", you are not allowed to solve it. If they say "help", ask what kind before you start. People rarely volunteer this, and almost always answer when asked.
Across 25 experiments, imagining another person's perspective did not make people more accurate about it. Asking them did.

They almost certainly think you think worse of them than you do. That's not insecurity; it's a measured, ordinary error: people on both sides of a divide put the other's dislike at about twice its real level, and after a conversation people underestimate how much the other person liked them.
Obvious to you. Not obvious to them. Say it anyway, out loud, more than once.

Small, boring, physical things — and they're better offered as a specific act than as an open offer. "I'll come at six and we'll walk" beats "let me know if you need anything," which puts the work of asking onto the person with the least capacity for it.
You cannot carry a lamp with no oil. If you are the one everybody leans on, you need someone to lean on, and time when nobody has access to you. That isn't selfishness; it's maintenance. Start gentle, as the old instruction has it: "first it must have an easy fire" (attributed to Roger Bacon, 1597).
When it's beyond you. If they talk about ending their life, give away what they own, or go silent and still after a long stretch of pain — stop being the only one. Saying "I'm worried, and I'm not equipped to be your only support" is not betrayal. It's honest.
In the US, call or text 988 (the Suicide & Crisis Lifeline) — you can call it for advice about someone else, not only for yourself. Elsewhere, your local emergency number.
"Do you want company, help, or to be heard?"
"Tell me what you actually want here, and what's underneath it."
"Let me say it back, so you can tell me where I've got it wrong."
"I'm not judging you. I'm glad you told me."
"I'll come at six and we'll walk."
"I'm worried, and I don't want to be your only support. Who else can we bring in?"
