How tf do you get over health anxiety

I struggle with health anxiety hard. Every day weird pains or something feeling slightly off terrifies me. It feels like everything in the USA is out to make you incredibly sick. Microplastics in our food, pollution in our air, allegedly more young people getting cancer.

I just want to be able to live carefree and not have to think about all this shit until later on in life. I am only 23.

What are y’all methods to cope with this?
