Have you looked up the crime stats for that area?
Without actually saying exactly where of course, but is it safe area at least?
If it is bad, I cannot understand living in such an area (I did for 7 years) as opposed to living in a fear free and mentally healthy, profitable area.
The helicopter used to go overhead in that 7 year period every night.
Shootings, stabbings and drugs were the norm. Not for me. I got out.
I'm sure Philly and Camden right across the bridge is much worse.
I hate to bring up the obvious, but some people have some form of disorder or mental illness that can't be helped by a lay person, no matter what is offered for help.
See the DSM-5
https://en.wikipedia.org/wiki/DSM-5. I'm sure you can find many that fit oneself and the people you know.
It doesn't make the person bad, only needing help that you cannot provide.
Sorry if it is an inappropriate post, but knowing that your world is about to crash around you (again) and not accepting sound advice would, be (in my opinion) indicative of something wrong.
I'm sure that a final $$$ drive for a suitable solution (not a band-aid) would be supported.
Only an opinion.
