I'm making that assumption because, according to the OP's own words, a psychiatrist diagnosed them with a mental illness because of the abnormal level of their anger.

I'm not missing the point of the post. The post wants to re-define illness. Like if I say we need to talk about the pathologizaton of Covid because my doctor said I'm sick because I have Covid, but I deny being sick because my fever, chills , coughing, difficulty breathing, sore throat, and runny nose are completely justified because I have Covid, so I am not sick.

The OP and everyone else here is missing the point of what the doctor is trying to say.
