The easiest way to get over your anxiety is to learn the fact that masks don't work. For starters, you can look up the diameter of a virus and compare it to the diameter of the holes in the mask: the virus is infinitely smaller and can easily pass through the holes of the mask if it wants. It's like putting up a wire fence to keep mosquitoes out.
There are zero double-blind, controlled studies that show masks work. One study, called the "Bangladesh study" that was touted by the CDC and others as the ultimate proof that masks work has long been debunked.
Sorry bro, you have been duped by the mainstream media. Masks don't protect you from airborne viruses. Their only purpose is to prevent you from contaminating things with your saliva. That's the reason the surgeons wear them, not to "protect" themselves from anything, but to not contaminate the medical field and the tissues of the patient they're operating on.
