I do agree that everything seems rather hopeless, current development seems more like walking backwards into a fire. But there are also people who try to make a good change for the environment we need to live somewhat comfortably.
I'm not too attached to life myself. The value of life seems to be emotional rather than logical. I'd be very upset if my own child chose to stop living, and she would definitely be upset if I stopped living. It's odd how I care more for other people's lives than my own.
I do not know what kind of encouragement you need, so I can't give you any of the sort. But I'll mention my own favorite reason for living despite it all: I really wish to see the end of it. The end of the world. Which is highly unlikely to happen any time soon, but that would be so awesome. Not that I want to see my own hometown burn down with people and myself in it, that would be terrible.
I'm thinking that I probably just need to move someplace else. Change my job. Do something different, meet other people than the ones I don't really meet nowadays. Wanting to live has a lot to do with having something or someone to look forward to. I just have to find that again.
