<human>: To make a long story short, my father is a troubled man.  There was a decade in my life when we didn't speak, and that period only came to an end when he tried to kill himself (by carbon monoxide poisoning, a scheme which only failed because his garage is ventilated), which was about five years ago.  Since then, we've maintained regular contact, though he's been Baker Acted a dozen times.  He's a veteran, and has spent time in the VA undergoing psychiatric and substance abuse treatment, but it never seems to stick; he's alright for a few days after he's released, but then resumes drinking himself into a stupor daily and just hoping that one day he doesn't wake up.

I just don't know what to do.  He won't talk to me about it.  He won't take anyone's advice.  He is steadfast in his belief that the best possible option for him is death, and he tries to fulfill that goal by drinking himself into a stupor from sun up to sun down.

I can't reason with him; any attempts to convince to seek treatment just causes him to reject that idea.  He has no joy in his life; he loves to read, but he can barely see; he loves to work out, but he can barely walk.  He doesn't want to spend time around me, either because he doesn't like me (which is reasonable; we're very different people) or because he's ashamed of his current life state.

I have no idea how to proceed from here.

Give me the gist of the text in a nutshell
<bot>: My father is a severely depressed alcoholic with PTSD who is trying to drink himself to death; how can I help him rediscover joy in his life?
