welcome how about printing off what you posted here and giving it to your psychiatrist to read? in my opinion that would be a great place to start...

also I can see why your psychiatrist and social worker would call this psychotic symptoms ....short version for some people what you posted is how psychosis/being psychotic affects them....hearing voices, perceiving others inside, having fears about other people places or things, getting short of breath, dizzy and all the other symptoms you have posted about are symptoms of the mental disorders that you have been diagnosed with (depression, psychotic disorder, anxiety....

another suggestion...there is a whole bunch of tests you can take that will tell you for sure if you have the mental disorders you have been diagnosed with or something different..testing for dissociative disorders like DID (one of the mental disorders where a person has alternate personalities) is very long and very thorough. your psychiatrist can tell you more about the diagnosis process for mental disorders and can administer some of the tests and a medical doctor will also need to send you for some physical\medical tests for all the medical things that this can also cause a person to have the same identical symptoms you posted about.
