It's perfectly reasonable for any rational individual to feel this overwhelming sense of nihilism. It's bad enough that life itself is meaningless, and this society humankind has built to surround itself doesn't help either. Capitalism, consumerism, hierarchies everywhere, money as the supreme value, people trying to take advantage of each other all around...

But as long as you can set all that aside for a few moments every now and then, and find the beauty in nature, find the peace in meditation, find the hope in the slight chance that people will all realize this one day and their attitude may change, it's a life worth living.
