I don't know if you've ever noticed that when you're tired, like really tired, doing the most simple tasks feel like moving mountains. They may make you angry, frustrated and annoyed. But you go to bed, wake up the next day and can take on any task. If you think about your current situation as "temporarily being tired", then you know some time later, you'll be feeling better. I use this kind of brain hacks all the time to snap out of spiral thinking. Give it a try.

I am in a very good place right now and yet I do NOT watch main stream news, regardless of what it is. I have recently started to script away negative content on HN and Twitter as well. So, cut yourself off from news. That alone should lift you up quite a bit.

The world is just fine. It's your fellow human beings who can't pay attention to anything but drama and chaos.

That's the spirit. Also, seek help from pros. Bunch of talking and some drugs can make a world of difference. They are not the cure, but a stepping stone, little push, to help you along the way.
