What do you do with a hopeless depressed friend?

He tried everything, he went through psychotherapy and it didn't help him, went through numerous psychiatrists and many psychologists and is tired of talking and refuses to see anyone anymore.
He tried different anti depressants but nothing improved the mood or situation.
Hospitalization didn't help at all and any further hospitalization will cause him even more suffering.
I just don't know what to do or talk about anymore, he only talks and thinks about suicide and is non stop saying how he doesn't care about anything anymore and accepted his fate (very recently)
Please help

He told me he plans 2 ways out, either with a huge overdose of benzodiazpines which he has an access through psychiatric prescription or crushing cherry pits to dust to consume and die from cyanide poisoning.
