You fail to mention the major neurotransmitter for mood being seretonin and noradrenaline. Dompamine of many versions D1, 2, 3 and so on is about perception and thought.
If your dompamine is screwed up you cant think = thought disturbance and also possibly your perception is altered and you here voices, smell strange smells and see strange visions, the latter 2 more likely indicative of an organic disturbance like a brain tumor or eg alcohol withdrawal not necesarily a functional psychosis such as schizophrenia.
If you have disturbance of sertonin and or nor adrenaline re-uptake you are likely to either be high or low being called manic or depressed. In both instances if the mania or depression gets bad enough it can influence dopamine and thus disturbances of thought and perception can occur with symptoms similar to psychosis.
Bare in mind there are levels of affliction in the above described, an if you have any of these symtoms I suggest you research assistances in the country you reside via google.
Have a great day
