Develop, or more like always had it AMD it just now surfaces due to the mental stress put on you by having covid (which isn't caused by covid but by how media reports about it, isolation and about how other people treat you?)

> The study also found that people with a pre-existing mental illness were 65% more likely to be diagnosed with COVID-19 than those without.

This sounds very misleading. I.e. it sounds like your are more likely to get covid-19 if you have a mental illness but that's not what it actually implies. More precise without additional information like the total percent of people tested which have mental illnesses, the consideration when it counts as a mental illness and how they don't someone had one and most importantly if they consider pre-test or pre-pandemy this can't be interpreted reasonable. Other missing parts include e.g. how likely someone with mental illness is to test themself compared to one which isn't.
