How do you guys cope with health anxiety through this all?

One thing that still haunts me after 3 Months of this, is the possibility that this all could be some other disease that i have, and not LC(although i am diagnosed and done a million other tests) but just the fact that with every new symptom i think its a sign of a new life threatening disease. I was never like this, i never even thought about sickness in this way, and now its all i think about :/ just in the last few days i have a little burning in the eyes and a little problem with my dioptry, and i accidentally read an article that covid leaves a bacterial infection in the sinuses that eats the brain and eyes, and i went into a full depression episode for days. Everything triggers me on tv or online or when people talk about illnesses, i just get chills and extreme anxiety
