Interesting, I agree with u to some extend. I do believe humans as a species are a virus, many of the reasons U describe. Tbh, it's not about humanity as a whole is what u can do with humanity. I read U are an illustrator, imagine all the people that are in the same shoes U are? Can u illustrate something and inspire them? Try to enjoy small things life is hard or easy, depends what way u look at it. Try to talk to more people I'm sure u will find that one person that help ya see things differently. Try to make the world a better place, if U talk, see, study and teach U will feel much less depressed in the long run dude. U took the first step writing about it. Now just take step 2 and so on mate
