Advice for people giving advice

Reddit is full of some very sad people saying very worrying things. Sure some might just be seeking attention, but it is very hard to scroll past comments from people who really seem to be in trouble. We can never know the difference.

I have just written an essay to someone trying to help, I try to engage in a meaningful way every now and then, but not one other person even addressed it.

Your answer might be- we can’t help everyone. But with the amount of people on this platform, yes we can, actually. We just choose not to.
