You can't shouldn't care to much, really. If everything bad you see makes you sad because you can't help, you you just life in sadness. I know it sounds hard, but that's how life works: The ignorant people who care about near nothing seem to be much "happier"(yet this way of life is nothing for me).
But you need to chose your own way, make your own experiences, that's why you should just do what you think is right, and maybe you can laugh about that decision in a few years because it became so unimportant.
Oh, and yes, I am bored.
