Yep. I have had some experience with folks in that condition.
I only know of one guy around here,,,
Worked with him many years ago,,,
He dropped out of sight after he and his wife split,,,
A friend who was a local cop and VFW member found him
living under a bridge,,,
They were able to get him into rehab and off the street,,,
I was glad to hear that he now has a job and is doing good,,,
Sadly many of these cases don’t have a happy ending...
