With respect, I think you're hung up on the literal definition of "mood", when in my opinion the term "mood disorder" is used as a softened, more socially-palatable euphemism for the more frank but intimidating label MENTAL ILLNESS, describing a state of dis-ease of the function of the brain, and you're wondering why your very serious symptoms of paranoia, delusions, and hallucinations could be dismissed as "disorders of mood". Bipolar disorder is euphemistically described as a "mood disorder", but as you know too well, you suffer from full-blown mental illness. That's my take on what you meant; apologies if I misunderstood.
