I know a few people who stopped on their own over the years but this has been rare in my experience but not impossible.
the disappearing is a sign of heavy use. My partner does this sometimes on a big binge, it’s so distressing when this happens isn’t it xx
but really I think they want to be left alone with their drugs and not have us killing their buzz and then are too paranoid and a mess to face us it seems but it is completely selfish and feels cruel and makes the whole situation worse.
im tired of it all
