This is years overdue, but I genuinely think that, as long as all of these vultures around Bam continue to enable him, he'll never get better. Dude needs to go completely off grid, locked in a room to go cold turkey, no Internet, no attention seekers around him, a decent mentor who will help him and not use that for their own gain or to appear virtuous. He needs to completely disappear from public life and get away from all of these arseholes if he's to stand any chance - he'll either end up dead or in jail if this carries on.
But it's probably too late for all that and he actually just needs sectioning. He clearly doesn't have the mental capacity to help himself at this point.
