There's this guy I know. I think I might be one of his only friends because he still talks to me about things that are going on in his life years after we last physically saw each other. Every time we talk I feel immensely shitty because he has these problems that are causing him a lot of stress and all I can really do is listen, ask little questions like "oh really?" or "and then what happened?" and give him normalfag tier advice like "you probably shouldn't beat the shit out of that dude your ex cheated on you with even though it would be really satisfying" or "you should consider talking to someone face to face about this stuff." I'm a kissless virgin with almost no social life whatsoever and when he talks about his relationship troubles I usually just end up parroting shit I've read on social media because I have no real experience to draw on. I'll say a couple prayers for him every now and then and pick up the phone when he calls but I wonder how useful I really am.
I get worried about the dude because he seems to have very few outlets and spends most of his time at work or alone and lately he's been under tons of stress due to work and his father passing away. He's been talking about how sometimes he just doesn't give a fuck anymore and I can tell what I say in reply doesn't really do anything for him even if I'm earnest about it.
It makes me wish I was the person he needed me to be instead of just another faceless incel loser weirdo who just so happened to meet this other person and be able to connect with him on some level. Not like in a "I wish this guy had someone else to talk to so he would stop bothering me" kinda way but more that I wish I could grow to be that better version of myself that I imagine sometimes, someone who could give good advice to others despite (or maybe even because of) his lack of relationships. I don't know if such a person can even exist but I hope he can.

Any books about people who heroically end all of their responsibilities and friendships and finally embrace and martyr themselves for the cause of alcohol?
