You can't do anything constructive for him at this or obviously any previous times , You know he's been bent on killing himself in this manner for awhile now . Do what you can to minimize any further damage .
Don't be surprised if he bounces back to a degree ( Doubtful but entirely possible ) , As you have seen here this disease can be unpredictable . Remember , He's been down that road and squandered all your valuable efforts . Far too often people aren't held accountable for their actions in life . Amazing thing is most of us know instinctively nothing is gained from a lack of discipline or consequence . Seems to me LJ has been living with that lack of consequence . I don't want to see anyone go through this but my gut tells me it takes this type thing to wake some people up .
