i'm gonna continue to wish him a speedy recovery
@SouthernComfort
, but i agree with shea...if he basically doesn't think there's anything wrong, that might mean he lost hope for himself, and it's up to you and your family to let him know there is still hope for recovery.
again, like shea said, i speak from experience myself as well, through a situation that's quite as similar as yours. i had an uncle who had heart problems, and would use cocaine and alcohol. his family tried to get him to stop, but it was too late. not trying to scare you at all, breh, because a breh don't deserve that. losing a family member hurts big time, and in addition to my uncle, i've lost a few others within the past couple of years.
stay strong and best wishes to your brother and family...
