It depends on what you mean by "help" really. I'm willing to listen to people and let them take whatever they need to out on me if they want to and/or talk about things, and I suppose that's a passive kind of help. Nothing is really an "off-limits" topic for me when it comes to things like this because it doesn't really affect me...a lot of people find darker conversations about things like suicide and self-harm upsetting for some reason even though they're not the affected party...I've never really understood that. But I digress - if helping someone is talking to them about their problems or thoughts in a calm, constructive, non-judgemental manner, then I am always prepared to do it. People need to talk sometimes. I never could when I was younger, and honestly to a very great extent I can't even do it now. It's isolating and incredibly difficult and not something I would wish on anyone.
But I'm not prepared to take a more active role in helping someone unless they ask for my advice and are prepared to at least give it consideration even if they decide not to follow it. You can't help someone who refuses to help themselves, or who doesn't want help but just feels like they have to ask for it and make a show of trying before giving up, which is what they actually want to do/have already done but feel like they can't or shouldn't because reasons. I've tried. So many times. It's exhausting, emotionally demoralising for everyone involved, and a colossal waste of time. I can't and won't get actively involved in other people's problems, because what would work for me might not work for them in addressing them, and if I'm honest about it I lack even a shred of empathy towards them. Maybe that sounds harsh or abnormal, but I need that detachment to protect my own mental wellbeing. I have enough shit to be getting on with and I'm not prepared to take on more. It's not fair to me, and it's not fair to them...having other people emotionally entangled in your problems often makes things worse I've found, because then you have THEM to worry about on top of everything else. I'd prefer not to become another problem, or treat them like a problem.
Basically, I'm a listening ear and occasional source of advice, and nothing more. If people want someone to care, they can find themselves a sympathetic friend.
Otherwise...I'm not in a position to help people financially, and I wouldn't unless I was obscenely rich and I knew the person well enough to know that they would make the best use out of the money I gave them...and that they'd pay me back in a timely fashion. Money is a valuable commodity that I have far too little of to go handing it out. But I'm willing to do small acts of kindness as and when if I don't have to go too far out of my way to do them, because it's just the decent thing to do, and if it doesn't cost me anything, then why not. Sometimes it's just nice to do something small for someone else's benefit.
