Sometimes no matter how much we want people to sort themselves out

it is just not going to happen.
Watching getting their life back together, making forward progress gives me a good feeling.
Then there is a break of months where there is no contact.
Contact is reestablished and I find out that person has crashed again.
Gone back to old habits, drinking, drugging, jobless, directionless.
Eventually one needs to let them go to get through life how they see fit.
And difficult and sad as that is.
