Hi. Nice to meet you, although I'm sorry about the circumstances.
I too was in the hospital with a failing liver, complete jaundice from top to bottom, yellow as a neon sign .. and in very bad shape. I pulled through AND it was the wake-up call I needed to stop drinking forever. In a twisted way (or maybe not so twisted), I am thankful that that happened to me.
I wish the same for your brother ... Hopefully they can get him in working order again and he will recover and have another chance to take his life in a great new direction.... I can imagine how helpless you must feel from so far away, but remember prayers or positive vibes and thoughts are wonderful things and do go a long way ... Stay positive for him.
Hang in there, and please keep talking about it on here, and keep us posted ... it helps to talk it out, especially among those who understand.
