Bewise- I hear you. Some days it seems like we would be doing the planet a favor if our species went extinct already...
But. I do believe that human race is mostly good. It's the big things you hear about in the news like terrorism and violence etc that can make us feel like our species is doomed.

But I believe that it's the little things I see every day that restore my faith in humanity, like coworkers donating toys to the needy, or a kind driver actually letting me pull in ahead of them, or a stranger at a group smiling at me to make me feel more comfortable, or a neighbor who walks across the street to give me a mail package of mine that she found in the road by my car...
I try to focus on the small goods rather than the big bads. Idk if that helps at all. Hang in there.
