> I've struggled for answers, but I don't think there are any.

It took me a long time to learn this: there are problems for which there is no answer.

I got this from Buddhism (I have renounced Buddhism, but I've retained some of the insights). The world is intrinsically fucked-up, and not fixable. You can sometimes fix some things, but in the end the world is an incorrigible mess (samsara).

It's quite a relief once you take that on board. You can go on raging against injustice, war, and political cynicism, and so you should; but there's no need to feel inadequate because you don't know how to fix it.
