Agreed & also readily advertise / make it clear what the suicide prevention and mental health support links, numbers & networks are. Have those numbers clearly listed in public places so that people are reminded that "help" is out there - just have to reach out and ask for it, or hopefully have someone encourage you to do so.
Credit also to the places like drop-in centers or food shelters / soup kitchens for helping people out. Ensuring people have a sense of community, friendships & of course access to food.
Some of the most rewarding work I've done is at the cold / wet weather shelters back in the day earlier in my career. Ensuring people were safe and sound, had a place to get back on their feet & resources we could offer them. Simple stuff - a bed (whether for a few days or up to say 3 weeks), food, shower, getting their laundry done, getting phone numbers and contacts to reach out for volunteer or part-time work, and so on.
Helping people get back on their feet, as the saying goes. Also hearing peoples' stories and ensuring their info/contacts were in the database so we had an idea how people were doing. Also - they could refer their friends to us who were down on their luck and living on the street ... fleeing a toxic home situation, etc. Refer them to treatment programs if they were looking to detox, etc.
