Tone matters, like the difference between telling someone they should consider seeing a therapist, and telling someone they need a therapist.

In text it is still hard, but convincing someone to talk to a professional (not saying they are all doctors or something) because you don’t feel equipped to handle the situation on your own shouldn’t be devastating if you go through a small course like that. Never taken one but just off the cuff I’d say offering to call with them and staying for the conversation until you/they agree they feel comfortable carrying on with the help line or what not on their own before walking away would probably be a decent step in the right direction. The line could advise you of the next steps you might not be thinking of in that moment, getting them around other friends/family/bringing them to a medical professional, I’m sure it varies.
