Things don't hurt you, the way you relate to them hurts.
No one is going to outright save us. We can't outright save anybody else. There are no prizes or rewards waiting for us in the end to award/punish us for the life we lived. There is no inherent/essential goodness or badness in the world that would be centralized to some certain places/human beings/activities.
But we are all in the same boat. We can still be casually nice and help one another. Another person can't "heal" you, but they can offer you a perspective, a listening shoulder, be your soundboard, give you experiences that make you see the life in different ways. And it works in both ways.
All you have to do is to accept. It's futile to wait for some deux ex machina, for those only exist in stories. It only creates sorrow to wait for something that isn't there. If you can accept it, you can shift your focus on real life, where the real healing is happening. We can help others heal themselves, it just doesn't happen in the way you except it to happen. Just because there are no godly interventions, it doesn't mean our ordinary caring for other people wouldn't matter. You can't judge those ordinary interactions just because you're excepting something else, something "bigger", that doesn't exist.
The ordinary interactions are all that matters, because we don't have anything else. It's "the real deal". And as such, it's a big thing, but we don't see that if we compare it to something bigger that doesn't exist. Drop those fictions, and you'll see the beauty in the ordinary. Change how you scale the world; your scale right now is being too wide.
You might know all this already. Sometimes it's just hurtful that the life is as it is and it feels good to outburst it all out, even if you were more realistic other times. Maybe we all have been there sometimes. I'm here trying to advise you but I've heard that every time people try to advise others, they're partly talking to themselves. Maybe I'm just trying to reassure myself here. Well, whatever, if this way of seeing things would help you as well, then it's all yours.
