Definition of "delusion" in DSM-5

[chimp3]

I am not changing the definition. Perhaps you are assuming that the DSM-5 is not a book detailing psychiatric disorders. Perhaps you want to trivialize the suffering of those people with schizo-affective disorder of the bipolar type, paranoid schizophrenia, dementia, brutal infectious processes which bring on delirium. Perhaps you want to equate these peoples diseases with a character flaw or a lack of intelligence.

I suffer from bipolar I disorder, OCD and psychosis. In the past, I've also suffered from hoarding disorder, BDD and PTSD. I've been in mental hospitals almost 10 times now. The first of those hospitalizations was involuntary, which is what caused the PTSD and simultaneously destroyed my relationship with my family. I take 900 mg lithium and 2 mg risperidone every night. This is why I was reading the DSM in the first place.

I am a 4th year math major who is planning to go to grad school. But due to my mental disorders I am only able to study part-time and I'll be 31 when I start my M.Sc. And you think I equate mental illness with a character flaw or a lack of intelligence. I have no words...

I suspect then that you should know the difference between a person taking the Eucharist and then going about their day and one having a psychotic break and needing a hospitalization and mood stabilzers and antipsychotics to go about their day.
Addendum: I am sorry for your personal struggle. I have no pity for anyone speaking in tongues on Sunday. One situation is voluntary, one is not!
