I’ve worked in outreach, either as part of my father’s worldwide ministry, as a volunteer or later as a paid professional for my entire life.
In the US today there are programs, facilities, options for those who are willing submit. How many people who come to my office as homeless, but, they will not take a space in a safe place because they won’t take a drug test or put their dog in a foster home or sleep in a women’s only facility while their boyfriend goes to the men’s ward.
Before I get a lecture about the dog, there was a time back during the 2008ish financial crisis when we lost EVERYTHING and we were 24 hours from homelessness. You bet your boots that I was as attached to my dogs as to my child, but, my child was a teen and the place where I could go allowed him to stay there as well. The dogs, I gave them away. Yes, it was sad, but, it was that or no roof over my head.
Except that there was a plan B. If I would have swallowed my pride and called my in-laws or my parents or my sister or my brother or my brother in law or one of my aunts or some old business acquaintances, they would have let us come sleep on the sofa or floor until we could find something else. I was too full of pride to make those calls, so, I gave away my dogs and most of my earthly possessions including my boat that we did not even have time to sell,and went to live in a place that was not pretty or comfortable.
Granted, I did not have a mental illness nor an addiction, but, I do have a profound physical disability that makes finding a job 10 Xs more difficult than an able bodied person.
Even for those with mental illness and addictions, I now live/work in a town of around 30K and do outreach into nearby small towns. IF someone is willing to be submit to the rules, I can find a place for them, and I am only one person. In large cities the resources abound.
I am sorry that no one offered to get you into a shelter or other program. I am sorry that no one pointed you to SNAP and food pantries and other places to eat. That does not negate the work that is done by a army of people who would be able to do more if they had more donations. We can stretch a dollar into two full meals! We just need people to donate those dollars.
