Can you emphasis on what exactly about humanity is making you have such a dim outlook on it?
Sure, the news is riddled with catastrophes, murders, and more often than not negative jargon that will otherwise give you a bleak outlook on the state of humanity. And yes, sometimes we're surrounded by people who otherwise want us to rip our hair out. But that doesn't mean that as a whole, we should hate humanity - there is a lot of good out there that gets unnoticed. It's just a matter of being at the right place at the right time to notice it, or better yet, become the change you want to happen in this crazy world that we live in.
There is a quote that I love from a women who's teachings I hold very dear to me: "I have this theory that if one person can go out of their way to show compassion, then it will start a chain reaction of the same. People will never know how far a little kindness can go." Become that chain reaction mate, and maybe you can convince others like yourself that the world isn't so bad as it's made out be.
