I mean, that's up to you. But I guarantee you will both feel better and maybe help save the world if you try doing something beyond getting angry and then disassociating.
Consider the fact that headlines that instill fear and doom work against us. What use is trying if it's all fucked anyway? The thing is it isn't over until it's over. I can't make you have hope, but hopefully you can come to realize that hope does a lot more for us than giving up. If you can envision a better future, you can work towards it! You can help advocate in your local Citizen's Climate Lobby chapter, develop a good garden for local wildlife and pollinators, or even just helping others be aware of the issue can help. There's no one coming to save us, so it's up to us to save ourselves.
Or you can just get angry and do nothing.
I understand the anxiety. I was frozen from it for a long time. But what helped more than anything else was simply going outside and tending a garden. Find a love for the life on this planet, and try to protect it. There's so much worth fighting for.
I'm glad you're doing something, despite the pain you're in. I simply want bring your attention to the fact that the doom and gloom attitude is harmful for the fight. In fact, many consider the onslaught of apocalyptic headlines and the new industry of climate fear to be a new tactic to get people to do nothing. Michael E. Mann, famous climatologist, has talked about this problem as well.
