Ask HN: How do I keep climate change from wrecking my mental health?

Title. I'm a 20 year old college student with an anxiety disorder, and that makes it fairly hard to not hit thought spirals. Particularly, climate change. I'm a vegetarian and I don't drive much at all, I don't use Amazon, etc. but I still have a hard time not just _thinking_ about it all the time and it's starting to affect my mental health. Obviously, we should all be scared as shit, but I don't know if it's healthy to feel this way all of the time if I've already taken steps.
