Kind of. It’s perfectly natural to feel afraid. And one will inevitably get symptoms when the physical bodily structures built to help cope with the fear inducing conflict are purged upon resolution of the conflict. That is all real. The mental illness part is thinking anything unnatural is happening and then doing irrational things like wearing masks, taking ivermectin, getting vaccinated, or anything that is oriented toward ‘trying to prevent nature from taking its course’. And the biggest part of the mental illness would be believing that there is actually a virus and fearing it in the first place.
