There’s evidence that trigger warnings actually worsen anxiety and are counterproductive
The way to treat anxiety is to face the source of anxiety to try and change your relationship and reaction. The best way to do this is via controlled access that exposes one to the trigger gradually in a context that has no risk of harm (eg a media depiction, discussing the concept, building up to discussing the source of trauma that led to the phobic response if applicable)
Trigger warnings enable active avoidance. This sensitizes one to the aversive stimuli and makes the phobic response stronger. As a result when one encounters the stimulus (eg a friend, family, celebrity etc commits suicide, suffers an eating disorder, etc) your resilience to the trigger is now even lower and the response is more likely to be more significant than it was before.
That said education on access to resources like 988 or other warm lines can lower suicide rates, maybe. Research is more mixed here because it’s difficult to prove causation
I worked homeless outreach in a rural area. My job was to connect people to housing, assist with obtaining government benefits, and mental health services if necessary. They would spend the day at local hot spots, well trafficked convenience stores in the morning, well trafficked stores like the local grocery store for most of the rest of the day. A lot of them would hang out in the stores as long as possible to escape the heat/cold and many would also hit up strangers for money at these spots
They were often very hesitant or completely unwilling to share where they actually slept. Even though I worked for a nonprofit a lot of them saw me as a government employee and even the ones who didn’t still were very hesitant to trust me or any of my coworkers with that info. I’m pretty sure they were scared that I would call the cops or something. Some slept in wooded areas, some slept behind stores, some couch surfed, etc from the ones who did share and who I found (part of my job was being the point of contact for police and other emergency services who found people staying outside in dangerous weather and getting them emergency housing).
Even though it was probably like 2013 or so that I did this job the absolute cheapest room that would rent to the homeless was $700/mo. There were cheaper rooms around but they tended to require big deposits and would often refuse to rent to someone that didn’t already have a permanent address. I’m pretty sure that’s illegal but they would get around it usually by being vague and ghosting. “Oh so sorry someone else got the room”, stuff like that, and you’d see it was still available for 3 more months. I can’t even imagine what the rent is like now
Super depressing job. It’s very difficult to escape that cycle once you’re in it. It radicalized me a lot to work with people who were literally left on the street in a town with hundreds of vacant apartments. By our estimate there were maybe 20-40 homeless people in said town at any given point
