I have constant thoughts about how Covid-19 might end or very badly affect most of the world (I "know" it won't but I can't get it out of my head), and it's making me feel really anxious. I have a lot of anxiety about getting Covid and how I could die or get a life-long illness from it, and my family that I still live with isn't careful about Covid at all for the most part. We're all vaccinated but I'm still very worried. How can I deal with these thoughts and general anxiety about this? Thanks
