Sorry, I only had your words to go by, and without the non verbals it is hard to read them, or write them, clearly all the time. What is correct then?
I just read you say:
"I think the advantage of a social support FROM HOME is that I'm always at my computer. "
The disadvantage is that it hasn't produced the sobriety you are still looking for in staying home and isolating.
Do you go shopping for food. Go out to doctor and barber appointments? You do need to take breaks, eat, exercise, and study how to lick your DOCs.
You asked for suggestions and mine was to re-examine your premises. Still is.
