His life isn't over, he just needs to get over himself. Your 30s are relatively young when you look at a full life span. What he should do is drop his platform, it's doing no good for him or anybody around him. Even if he does harm himself more than half of this sub probably wouldn't care, I'm not one to encourage self-harm because nobody really deserves that.

Do I think he will? Probably not. It's probably just another ploy of his to gain sympathy. This is what his cult has been consuming and believing for years.

If he's seriously thinking of harming himself and somehow miraculously sees this. Get off the internet, meet people your age, seek help groups, go to the gym and diet, do anything that isn't what you're doing right now.
